How Does the Exponential Growth of Bacterial Cells Affect Their

How does the exponential growth of bacterial cells affect their genetic diversity?

A) The greater the number of cells, the greater the expected number of spontaneous mutations.
B) It does not affect genetic diversity because binary fission is an asexual means of reproduction.
C) Spontaneous mutations are repaired by enzymatic repair mechanisms and therefore do not last long enough to cause a mutation.
D) Most spontaneous mutations are lethal therefore the mutated cells would die out and not reproduce.
