If I see my friend preparing her/his fish for cooking, and I wonder what kind of fish it is, what is the suitable sentence to ask her/him?
(a) What kind of fish will you use?
(b) What kind of fish are you using?
(c) What kind of fish do you use?
Is there anything wrong if I use the present simple tense because I just want to know the general information?
I am afraid of overusing the continuous tense in speaking.
