Answer 2

I would have to say A, mitosis.

I say this because Mitosis produces an exact replica of the cell, thus not contributing to biological evolution.

B allows a species to adapt to harmful environments.

C allows for variation within a species and D produces variations as well within offsprings.

Hope this helps!
