Question

Who is your favorite band? / What is your favorite band? / Wich is your favorite band?
What's the right way to ask that question?

Answer

The proper way to ask this is "Who is your favorite band?" Bands are people, and people are who, not what. I hope this helps! :)

Answer

What is your favourite band? (favourite spelt the UK spelling)

Answer

What is your favorite band? and  Wich is your favorite band?

Answer

I would go for the "What is your favorite band?" and "Which is your favorite band?" (The band itself is not a person)

Answer

All three are correct.
