Answer:
A
Explanation:
Natural selection occurs when an environment makes organisms with certain traits more likely to survive and reproduce.
Asexual reproduction results in no genetic variation (meaning differences in traits, also called divserity). Genetic variation must be present for certain organisms to be better suited to their environment, because in its absence all organisms share the same traits. This rules out B, C, and D. I hope this helps :)

Answer:
B
Mutation is the ultimate source of genetic variation, but mechanisms such as sexual reproduction and genetic drift contribute to it as well Because prokaryotes are haploid, such a mutation immediately become part of the genetic makeup of the cell unlike eukaryotic diploids where a normal second copy of the gene usually protects the cell from the potentially lethal effect of such a mutation.
