<h3>What is Evolution?</h3>
This is described as the process in which heritable characteristics are changed in species over successive generations. This occurs as a result of natural selection in which the traits suitable for survival are passed to the offspring.

Answer:
The correct answer will be option D.
Explanation:
DNA replication is a complex process which forms the exact copy of the DNA molecule from the existing DNA. This process takes place during the synthesis phase or S-phase of the cell cycle which takes place in the cytosol of prokaryotes and nucleus of the eukaryotes.
The most common way of producing replicas of the DNA molecule is through semi-conservative mode in which each strand of DNA is synthesized from both the strands of the parental DNA using as a template.
Thus, option D is the correct answer.
