(b) Toads

(c) The fish

(d) alternative b and c

(a) Los gatos

Explanation:

Only cats are capable of internal fertilization from the given choices above.

Internal fertilization is the fusion of gametes within an organism. This process occurs during sexual reproduction within the female.

In cats, the female specie takes in reproductive cells from the male during coitus and it fertilizes the her eggs to produce a zygote.

the corpus luteum secretes estrogens and progesterone. the latter hormone causes changes in the uterus that make it more suitable for implantation of the fertilized ovum and the nourishment of the embryo. if the egg is not fertilized, the corpus luteum becomes inactive after 10–14 days, and menstruation occurs.

b is dominant over the allele for the white fur.
