In Option 2, all the structures listed - nephridia in earthworms, Malpighian tubules in cockroaches, and urinary tubules in rats - share a similar excretion and waste removal function.

Nephridia in earthworms are tubular structures that filter and remove metabolic waste from the coelomic fluid. Malpighian tubules in cockroaches perform a similar function by removing nitrogenous waste and maintaining water balance in the insect's body. Urinary tubules in rats, specifically the nephrons in the kidneys, filter blood and eliminate waste products in the form of urine.

Therefore, Option 2 represents a group of structures/organs with similar excretory functions.
