Two students made models of a population of bacteria before and after they were treated with an antibiotic for several generations. Use the models to answer the question. Which statement below best explains why one of the student’s models is more correct than the other?

A.
Student A has the model that is most correct, the model shows how some bacteria changed themselves in the initial population of bacteria which led to those bacteria surviving the antibiotic while the other bacteria died off.

B.
Student A has the model that is most correct, the model shows variation in the initial population of bacteria which led to some bacteria surviving the antibiotic and reproducing while the other bacteria died off.

C.
Student B has the model that is most correct, the model shows how some bacteria changed themselves in the initial population of bacteria which led to those bacteria surviving the antibiotic while the other bacteria died off.

D.
Student B has the model that is most correct, the model shows variation in the initial population of bacteria which led to some bacteria surviving the antibiotic and reproducing while the other bacteria died off.
