Answer: 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.
Since the new line of cats are genetically modified to eliminate or reduce their allergy-causing properties, then we can infer that the DNA of the cats have been manipulated. In this case, the allergy causing property won't be passed across to the offspring since the DNA has been manipulated.
