One current theory of why cancer cells can replicate so rapidly and why they may, in fact, be able to live with no time limits, is because they
A) are not susceptible to the "programmed" longevity in one's genotype.
B) are immune to the destructive nature of free radicals.
C) have the ability to activate telomeres on the tips of chromosomes.
D) replicate human cells so perfectly that they human body cannot fight them.

Cancer cells have the ability to activate telomeres on the tips of chromosomes, which enables them to divide indefinitely without reaching a limit on the number of divisions. This is because telomeres protect the ends of chromosomes from shortening during cell division, which can eventually lead to cell death. By activating telomeres, cancer cells circumvent this natural process and are able to continue replicating rapidly without any time limits.
