A more positive way of expressing a lack of preference would be I don't mind.
--Where should we go? To the cinema or the park?
--____________. Anywhere you want.
A. Never mind B. I don't care C. I'm in no hurry
I think none of them fits in this situation. "I don't care" shows that the author shows no interest and is not a positive answer.
Am I right?

I disagree that "I don't care" means "no interest." It's not a very nice way of saying "I have no preference" but it could be that the person thinks that either of the choices are equally agreeable and anticipates a pleasant outing at either one.
I'm not a teacher, but I write for a living. Please don't ask me about 2nd conditionals, but I'm a safe bet for what reads well in (American) English.
