(C) A-III, B-IV, C-I, D-II
Solution & Explanation
Answer: (C) A-III, B-IV, C-I, D-II Solution: Cocaine is obtained from Erythroxylum coca (A-III). Heroin is acetylated morphine extracted from the poppy Papaver somniferum (B-IV). Morphine is a very effective sedative and painkiller, useful in patients who have undergone surgery (C-I). Marijuana is a natural cannabinoid from Cannabis sativa (D-II). Why others are wrong: Linking heroin to Erythroxylum or cocaine to Papaver swaps the source plants; only C matches each drug to its correct plant/use. NCERT Reference: NCERT Ch7, p.143, lines 6-8, 15-16, 30-31; p142 line 35-36: "Morphine is a very effective sedative and painkiller, and is very useful in patients who have undergone surgery"
