I'm looking for a Javascript that makes the following: I have a list of questions with three answers each. I would like to have the following behaviour: on rollover the correct answer should change to green color. Somebody can gives me a good hint?

Example:

Question 1: how much is 2+3?
a) the correct answer is 6
b) the correct answer is 5 On rollover over the question "b) the correct answer is 5" should change to green
c) the correct answer is 4

Thank you
