Can someone help me with this mutation question? I have it narrowed, but I'm not sure... "What is one condition necessary for a mutation to persist in a population?"
A. The mutation is only lethal in the homozygous recessive state.
B. The mutation provides an advantage under certain conditions.
C. The mutation does not affect selection.
The mutation increases reproductive advantage.
D. The mutation has a minimal affect on adaptations.

I think it's A. Because a mutation can occur and continue in a population, as long as it doesn't kill them, right? 
Any other ideas?

i go forr b

but being an advantage under a certain condition isn't /necessary/ per se, is it? i mutation could be neutral and still persist couldn't it?

I don't think B is right. Mutations can persist by chance (it's called genetic drift). I am inclined to go with A.
