Answer 2

I would speculate that since selective breeding and artificial selection are synthetic processes, A conservation biologists, who actually wishes to study earth's natural biodiversity and aims to conserve it, will be least bothered by these processes. That leaves us two options.

The fourth options looks more intuitive to me.
