One advantage of sexual reproduction is that animals can:

A. increase their numbers rapidly.

B. create genetic diversity.

C. adapt to environmental change rapidly.

D. produce offspring that are genetically identical to their parents.

B. create genetic diversity

Because you can't increase number rapidly and you cant adapt quickly because of the same reason and people are not identical to their parents. Therefor B is the only answer and if you look at the human race we are all very diverse.
