The correct match between Item-I and Item-II is:
Item - I (drug) and Item - II (test)

Answer: A → III, B → IV, C → I, D → II

Solution

Match each drug to the functional group it reveals. Chloroxylenol is a phenol, so it answers the ferric chloride test with a coloured complex. Norethindrone carries a carbon-carbon triple bond, so its unsaturation shows up in Baeyer's test. Sulphapyridine has a free primary amino group, which gives the foul-smelling isocyanide of the carbylamine test. Penicillin bears a carboxylic acid group, so it liberates in the sodium hydrogen carbonate test. The pairings are chloroxylenol with ferric chloride, norethindrone with Baeyer's, sulphapyridine with carbylamine and penicillin with sodium hydrogen carbonate.
