Hi,

I think that you're missing some options, but here they are (let me know if I'm right!

-A population of wolves was introduced
-The amount of disease in the deer population decreased
-More grass was planted

Now, if the gene diversity decreased, it means that a lot of deer died. This could happen because wolves were introduced -this is the correct answer, and the wolves ate some deer.
