Concept: In this vocabulary-analogy style, each pair links an animal to the single word CONVENTIONALLY used for its foot or limb — the standard, most commonly cited term for that animal's foot, not a term that must be anatomically exclusive to that one animal. Even the stem's own first pair is built this way: 'paw' is not unique to cats (dogs and many other animals have paws too), yet 'paw' is still the default, expected term for a cat's foot. The same convention applies to the second pair.

Application: Applying that same convention, the single word most commonly and conventionally used for a horse's foot is 'hoof' — just as 'paw' is the default term for a cat's foot even though other animals also have paws, 'hoof' is the default term for a horse's foot even though other hooved animals (such as sheep/lamb) also technically have hooves.

Cross-check — why the other options don't fit:

• Dog: a dog's foot is also called a paw (like the cat's), so pairing it with hoof breaks the analogy rather than completing it.

• Lamb: even though sheep/lamb technically have hooves too, in this word-pairing convention lamb/sheep is identified by the term 'wool', not by a foot-term — just as dog is excluded despite sharing 'paw' with cat, lamb is excluded despite sharing the physical trait of hooves; the analogy tracks the conventional term, not raw anatomical overlap.

• Elephant: an elephant's foot is not termed a hoof at all; it is a broad, padded foot with nail-like toenails.

So the correctly paired term is hoof : horse — the conventional, most commonly cited animal-to-term pairing this analogy tests, paralleling paw : cat.
