Which one of the following could be a complete and accurate list of the animals kept in cages W and Y?

A & D

Unlike the previous post, I have not figured it out. I don't understand why it can't be both A & D.

In D, we have three lizards and a snake together. This means we have used up all our lizards, but we still have four more snakes left to place. However, the rules tell us that if snakes then lizards, so there is nowhere for our other snakes to go that wouldn't violate this rule.
