The development of this new line of cats most likely involved A. using natural selection to produce a new variety of cat B. altering the reproductive rate of cats C. changing the behavior of cats D. manipulating the DNA of cats

D. manipulating the DNA of cats.

Explanation:

Deoxyribonucleic acid (DNA) refers to the organic chemical which consists of genetic information. The DNA can be found in the cells of organisms.
