columns

I have 5 columns corresponding to answers in a trivia game database - right, wrong1, wrong2, wrong3, wrong4

I want to return all possible answers without duplicates. I was hoping to accomplish this without using a temp table. Is it possible to use something similar to this?:

select c1, c2, count(*) from t group by c1, c2

But this returns 3 columns. I would like one column of distinct answers.

Thanks for your time
