What will you make

Hello everyone. I have a question.

I want to make a short dialogue which sounds natural. Is the following one okay?

Bob: I'll make dinner tonight.

Nancy: What will you make?

Besides, I've made a couple of sentences to replace Nancy's line. Can they all work? Please evaluate each of the three sentences below.

(A) What do you plan to make?
(B) What are you going to make?
(C) What are you making?
