Humans have backbone and hair, and they are warm-blooded. So, R can be a Human Being. So, this statement is Correct.B. Q could be six-legged animal whereas R could be four-legged animal. ----- Spiders have six legs and they lay eggs. So, Q can be a Spider. Horses are four-legged animals. They have backbone and hair. So, R can be a Horse. So, this statement is Correct.C. R could breathe through lungs whereas S could breathe through spiracles. ----- Dogs breathe through lungs, they have backbone and hair. So, R could be a Dog. Cockroaches breathe through spiracles. They have backbone and lay eggs, but they have no hair. So, S can be a Cockroach. So, this statement is Incorrect.D. P could have a pair of wings whereas Q could have two pairs of wings. ----- Birds have a pair of wings. They have backbone and they lay eggs. So, P could be a Bird. Most insects have two pair of wings, and they lay eggs. So, Q could be an Insect. So, this statement is Correct.Hence, the right answer is Option C.
