Based on your understanding of Darwin's Theory of Evolution, which of the following organisms would potentially evolve the fastest ?

A) All of these species would have roughly the same rate of evolutionary change

B) A species of roundworm that reproduces via asexual reproduction but contains a DNA replication machinery that introduces 3-6 mutations every mitotic cycle with a generation time of 6 days

C) A species of mammal that reproduces sexually and passes on roughly 3 mutations every generation with a generation time of 18-20 years

D) A species of bacteria with a poor DNA replication error correction capability that normally reproduces asexually but can reproduce sexually and has a generation time of 45 minutes
