If you sampled the genetic characteristics of a large population and found that of the 50 loci analyzed there was very little if any variation, the most likely explanation would be that
a. a uniform environment selected for these alleles.
b. there has been a lack of migration and the genetic equilibrium stabilized the population.
c. strong selection pressures eliminated alternative alleles.
d. a bottleneck effect may have occurred in the past to reduce the variability in the population.
e. a combination of low mutation rates and differential sexual
selection produced these results.

I agree that this indicates a bottleneck: answer D.
A bottleneck means that the population traces back to few individuals, not back to a large population.
