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.
