My parents are both doctors and they gave me the right, 100% accurate answer. I don't think I can post it here until 24 hours pass. Whoever wants to know it can inbox me, and I will offer an explanation. ^.^

I think the cats one was C, the female is heterozygous.
The question stated that A SHORTHAIRED FEMALE gave birth to 5 kittens, 2 with long hair.
If she is SHORTHAIRED, her possible genotypes are SS or Ss
If you take it to be SS, then you will not get the 1:1 ratio of the kittens phenotype as all will be shorthaired kittens
Therefore, we know for sure that the female is heterozygous in order to provide the recessive allele.

Plus, this option was more specific.'One parent is homozygous' is part true because it doesn't tell which one, male or female.
