- D.A–III, B–II, C–I, D–IV
Correct Answer
(C) A–II, B–III, C–IV, D–I
Solution & Explanation
Answer: (C) A–II, B–III, C–IV, D–I. Solution: Nicotine (A) stimulates the adrenal gland to release catecholamines (adrenaline/nor-adrenaline) into the blood → II. Morphine (B) is a very effective sedative and painkiller → III. Heroin (C) is a depressant that slows down body functions → IV. Cocaine (D) has a potent stimulating action producing a sense of euphoria and increased energy → I. Why not the others: The other options misassign morphine and heroin (morphine = painkiller/sedative III, NOT depressant) or swap cocaine and nicotine, so only A–II, B–III, C–IV, D–I is fully consistent with NCERT. NCERT Reference: NCERT Ch7, p.143-144 (heroin p.143 l.3-4; cocaine p.143 l.18-21; morphine p.143 l.30; nicotine p.144 l.6-7): "heroin is a depressant and slows down body functions"
