Final answer:
The options given don't offer an accurate biological answer to how a dog would smell without its nose. Dogs use their noses for smelling and without it, they would rely on other senses.
Step-by-step explanation:
The question 'My dog's got no nose. How does it smell?' is a classic format of an English joke. However, without the humor, the literal biological answer is, dogs primarily use their noses to smell. Without a nose, a dog would primarily rely on its other senses to interact with the world around them.
So the answer choice 'c) Through its ears' is incorrect because ears are for hearing, not smelling. And, the answer 'd) Like a dog' is too vague as it's not particular to the question about the dog's ability to smell without a nose.
The other two options a) Terrible and b) Fantastic, give a subjective interpretation of 'how the dog smells', which implies an opinion about an odor rather than a functioning sense of smell. Neither of these choices answer the biological fact accurately.
