D Correct answer
Explanation

All parts of Datura plants contain tropane alkaloids - atropine, hyoscyamine and scopolamine, which are classified as deliriants or anticholinergics. Atropa belladonna contains active agents in belladonna, atropine, hyoscine and hyoscyamine, and have anticholinergic properties. Solanum dulcamara contains the alkaloids, solanine (from unripe fruits), solasodine (from flowers) and beta-solamarine (from roots). Hence, P and Q both produce atropine alkaloid.
