@ZairaHernandez  If you lose 90% of the population, do you think that inbreeding will decrease?  What if you lose all but two males?  This means the entire population will be closely related to these two males, so lots of inbreeding.

Bottlenecks remove genotypes.  What if we have a species with two behaviors, and one behavior allows for adaption to the environment but for some reason these better adapted individuals are all wiped out.  We would only have the individuals that sucked at adapting.

I just said the population loses genotypes.  So, we know that they do not retain genetic diversity they lose it.  

The answer is therefore C.
