The correct answer is: D.New genetic material does not enter the gene pool.

Explanation:

In the context of Hardy-Weinberg equilibrium, the assumption of no mutations means that the genetic material in the population remains stable, and no new alleles (genetic variations) are introduced. Mutations are a primary source of new genetic material, so if mutations are absent, the gene pool remains unchanged, and the population does not evolve in terms of new genetic variations.
