Why is the statement in the question stem not a subsidiary conclusion?

From the evidence of whiskers which I understand is a premise, it seems like they conclude that this animal must've had fur. From that, the author then concludes this animal its warm-blooded. How do I know that it's a premise and not a subsidiary conclusion? This is the reasoning that led me to answer choice C.
