Answer:

The preferable option will be - A.

A. The population will eventually become monomorphic for one of the two alleles.

Explanation:

The population will eventually become monomorphic for one of the two alleles because  -

  • Here mutation is absent.
  • No other allele is allowed to get involved here.
  • The population size is small.
  • As allele A and B are fixed for that population after many generations the population will become monomorphic for that two alleles.
