Hello

Here is a cup of coffee.

If one refers to the thing above, in what way would one say?
A. the cup of coffee
B. the cup of the coffee

Thank you

A.

B is technically correct, but it the second "the" is unnecessary and so looks very out of place.

Thank you for your reply

Does the speaker think as below?

The focus is almost on the cup. Almost no attention is paid to what or which coffee.

Thank you

 

[Williamer]

the cup of coffee is right.

Well, yes, all we care and want to know about is that there is coffee in the cup. You would use the article if you had defined or restricted the coffee, usually with a relative phrase: "here is a cup of the coffee you liked so much yesterday morning".
