The answer is B, since the population has no genetic variation it will be classified as an artificial selection not a natural selection.

Natural selection is least likely to be the cause of a change in a population's allele frequencies when: the population has no genetic variation. Thus, option (B) is the correct answer.

Natural Selection:

The change or evolution in the heritable traits characteristics of  population over the generation is called natural selection.

Four factors are required for natural selection:

  • Reproduction
  • Heredity
  • Variation in fitness of organism
  • variation in individual characters among member of population.

Thus, if the population has no genetic variation, natural selection will not happen. So the option (D) is correct.
