Explanation

The geneticists mentioned are studying a population descended from a rather small number of people a rather long time ago.

Geneticists — who study genes, of course — would be interested in how this population changed over time (mutated) and became different from one another (diversity). Note that none of the other answers are logical at all.

Hence options diversity, mutation are best fit!

Was difficult to narrow down between diversity/revivification. Please explain.

Shouldn't the answer be B. revivification and F. rejuvenation as Iceland has been able to repopulate from less than 1000 ancestors? That doesn't seem diverse.
