This type of construction calls for the bare infinitive—you cannot say, after all, “All we can do is to wait.”
Well, I’ve disagreed with Messrs Thomson & Martinet before, and unabashed I unhesitatingly rush to do so again!
1. As this question is one which the setter believes has a single answer, that answer must be B.
2. This type of construction calls for the bare infinitive—you cannot say, after all, “All we can do is to wait.”
3. I think the thread title should be changed to reflect its contents (for the benefit of future researchers).

Why?
Maybe because the modal can is used here, and can calls for the bare infinitive: all you can do is wait= you can only wait.
But the original sentence is different:
"All you have TO do is .. hard"
Since you have TO do something, then perhaps you should use TO- infinitive in the second part of the sentence as well. "You have TO study hard". "All you have TO do is TO study hard"
A matter of symmetry, the way I see it. Is this issue relevant at all?
Thank you

Well, I found the example under the following title: The bare infinitive after verbs and expressions, not the use of the verb can.
The same source provides this kind of example: "The only thing to do/we can do is (to) write to him."
This latter example highlights the difference perfectly - to do...to write match up perfectly; have to do/must do/can do/need to do...study all match perfectly.
It is so late that I might be wrong, but, to me, the sentence proves that the word to is optional.
If so, I've managed not to be clear
For example: it's not (want) to do, it's want to (do) - and therefore it's "study".
I bet that's not any clearer....oh dear![]()
According to the BBC:
http://www.bbc.co.uk/worldservice/learningenglish/grammar/learnit/learnitv226.shtml
after ‘must’ and many other modals, the bare infinitive only is used. Thus in the example, even though ‘must’ has been changed to ‘have to’, the effect is the same: all you must do is study = all you have to do is study.
For me, the bare infinitive is callled for, not because of the semi-modal in the sentence, but because of the "do".
"Do" takes the bare infinitive (I do go, you don't go), so in all you have to do is X, X is the bare infinitive.
If the sentence were all you want is X (X being a verb, not a noun), X would be the "to infinitive" because "want" takes the "to infinitive".
All you do is study.
All you have to do is study.
All he wants is to go out drinking with his friends.
Much as I agree with the use of the bare infinitive after modal verbs, the sentence in question appears to be a different kettle of fish. I think the key word is all, not the verb(s).
Would it be possible to claim that both answers are perfectly acceptable?
(If the source I quoted says so, there must be some reasons to put forward such a suggestion.)
I really can’t see that all makes any difference, audiolaik.
All you have to do is study.
What you have to do is study.
You have to do what you’re told—study.
And that last one might be the solution: it’s not too great a leap of the imagination to consider the bare infinitive in other examples to be, in fact, the imperative—which is why there would be no infinitive marker.
(But, when all’s said and done, I’m far less bothered by this grammatical superfluity (in my opinion) than others.)
For me, the bare infinitive is callled for, not because of the semi-modal in the sentence, but because of the "do".
"Do" takes the bare infinitive (I do go, you don't go), so in all you have to do is X, X is the bare infinitive.
If the sentence were all you want is X (X being a verb, not a noun), X would be the "to infinitive" because "want" takes the "to infinitive".

I do not know if it is of any importance, but I have just found the following sentence in a coursebook*:
What scientists do is to observe and measure the world around them, and attempt to....
*CAE Gold Plus, published by Longman
Well, course book or not, I think this is totally wrong and I am saddened. To correct it simply I would write:
What scientists do is observe and measure the world around them, and attempt to....
and if I wanted to be fussy (who, me?) I would say:
What scientists do is, they observe and measure the world around them, and (they) attempt to....
