Correct Answer
(C) (c) A-III, B-II, C-IV, D-I
Solution & Explanation
Answer: (C) A-III, B-II, C-IV, D-I. Solution: Matching each animal to its excretory structure: Taenia (a flatworm/Platyhelminthes) uses flame cells — protonephridia (III); Paramoecium (a protozoan) uses a contractile vacuole for osmoregulation (II); Periplaneta (cockroach, an insect) uses the uricose gland associated with its excretory apparatus (IV); and Pheretima (earthworm, an annelid) uses nephridia (I). NCERT notes protonephridia/flame cells in flatworms and nephridia as the excretory structures of earthworms and other annelids; the contractile vacuole and uricose gland are standard general-biology assignments for the protozoan and insect respectively. This gives A-III, B-II, C-IV, D-I, which is option (c). NCERT Reference: Ch 16, p.206, line(s) 6-11 — "Protonephridia or flame cells are the excretory structures in Platyhelminthes (Flatworms...). ... Nephridia are the tubular excretory structures of earthworms and other annelids."
