(3) A-I, B-II, C-III, D-IV
(4) A-I, B-II, C-IV, D-III
Answer: Option (1)
Explanation:
Taenia is a flatworm (Platyhelminthes) and its excretory organs are flame cells.
Paramoecium is a protozoan in which osmoregulation and excretion are carried out by
the contractile vacuole.
Periplaneta, a cockroach, possesses urecose glands (fat bodies) which help in excretion.
Pheretima, an earthworm, belongs to annelids and uses nephridia as its excretory organs.
Therefore, the correct matching is A-III, B-II, C-IV and D-I.
