Answer:
B) Post-zygotic factors prevented successful reproduction.
Explanation:
Postzygotic factors may influence the formation of the fertile offspring.
The postzygotic barriers basically involves the formation of the hybrid organisms which do not survive past the embryonic stages i-e hybrid inviability / the hybrid creation that is unable to form the offspring i-e sterile.
So , in the given scenario option B )Post-zygotic factors prevented successful reproduction is the right answer .

<h3><u>Answer;</u></h3>
It occurs over many generations.
It happens at the genetic level.
<h3><u>Explanation</u>;</h3>
- <em><u>Evolution is the process that involves change in the inherited traits of a population over generations. </u></em>
- <em><u>The traits involved are the expressions of genes that are copied and passed from the parents to the offspring during reproduction process. Mutations in these genes results to new traits and thus heritable differences among organisms.</u></em>
- <em><u>Therefore, evolution will only occur when there is change in gene frequency within a population over a given period of time. Genetic differences that are heritable are passed to the next generation.</u></em>
