Match List I with List II: List I (Drug) A. Nicotine B. Morphine C. Heroin D. Cocaine List II (Effect) I. Causes sense of euphoria and increased energy II. Stimulates adrenal gland to release catecholamines into blood circulation III. Effective sedative and painkiller IV. A depressant; slows down body function Choose the correct answer from the options given below:

  1. A.A–III, B–II, C–IV, D–I
  2. B.A–II, B–III, C–I, D–IV
  3. C.A–II, B–III, C–IV, D–I
  4. 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"
