Hello! I’m learning about Biotechnology and am confused on this question, “Most plastics tend to persist in the environment because natural processes do not degrade them effectively. A scientist thinks that a new strain of bacteria can be developed to break apart plastics. To develop this strain of bacteria, the scientist proposes to subject a colony of bacteria to powerful mutagens.” Which statement best explains why the scientist’s proposal could be successful?: A: Mutagens that are properly chosen can produce any specific trait.

B:Mutagens act to preserve beneficial traits and reduce harmful traits within a population

C: A specific trait becomes more likely as the genetic diversity of a population increases.

D: A specific trait becomes more likely as genes from other species are added to a population.
