I also agree that the answer is B: whom
in this sentence you are using the preposition + whom grammar structure. Whom is considered an object pronoun and is used when asking who will receive the action, which in this case, I believe is, baking those cookies. Hopefully this makes sense and good luck.
Answer: B. Wolf pack have alpha wolves that lead the pack.
Explanation:
A way that wolf packs keep the peace and work together is that the wolf pack have alpha wolves that lead the pack.
In a wolf pack, there's a social structure and there are rules that guide the pack. The alpha males and the alpha females are the leaders of the pack.
The alpha male and the alpha females have dominance over the other wolves that are in the pack. Anytime there is a kill, they eat first and they produce and also breed pups.
