b. The horse and donkey are not members of the same species because their offspring are sterile (not fertile).
c. The horse and mule are members of the same species because they can reproduce.
d. The horse and mule are not members of the same species because their offspring are fertile.

B. The horse and donkey are not members of the same species because their offspring are sterile.

Explanation:

The horse and donkey aren't members of the same species since the donkey has 62 chromosomes while the horse had 64 chromosomes and members of the same species need to have the same number of chromosomes. This leads to the mule having 63 chromosomes which is an odd number of chromosomes so it is sterile.
