What is true of natural selection? A. Natural selection is a random process. B. Natural selection creates beneficial mutations. C. The only way to eliminate harmful mutations is through natural selection. D. Mutations occur at random; natural selection can preserve and distribute beneficial mutations.

Explanation:
natural selection can simply be explained as individuals that have specific inheritable traits will most likely tend to adapt and survive and as well reproduce at higher rates than others. mutation occurs when the nucleotide sequence of an organism changes. so natural selection can preserve and distribute beneficial mutations.
Answer:
Option B, Cellular clock theory
Explanation:
The Cellular Clock Theory of Aging states that the older the cells get , the more they become incapable of reproducing or replicating. The telomeres (tip of the chromosomes) are DNA sequences which cap the chromosomes get smaller in size with time and eventually they hinder the cell division. As per a normal standard rate, a telomere replicates 70 to 80 times in its life span and then it stops replicating.
Hence, option B is correct
