How to show 1 answer at a time in a quiz

I have a quiz where you can see some information about an answer whether it is wrong or right after you submit. After you click on submit, all 3 informatic texts about the answers are shown instead of just for the answer u clicked. How can you make it that when you click answer A, information A is seen ? And not Information A B C.

SO to summarize: How to make only 1 explanation at a time visible after you change your answer ?
