Answer:
Option B, Cellular clock theory
Explanation:

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
