The box's weight/the weight of the box

[nnasi]

i have some questions with the following exercise:
_____is too much for the boy to carry.
a) The box weight
b) the box's weight
c) the weight of the box
d) the box of weight
the correct answer is b, but why it can't be c?
i think that b and c are the same.

For me, both B and C are correct. So, I agree with you.

I agree that both (b) and (c) are grammatical, but I would add that (c) is much more usual than (b).
The Google Ngram Viewer confirms this. (If you go to the Viewer, click "Search lots of books".)
(Nnasi, always capitalize the pronoun "I" and the first word of a sentence.)

I agree - C would seem much more natural to me.
