Clove, a spice, is obtained from which part of the plant?

Correct answer: (d) Flower bud

Explanation

Clove (Syzygium aromaticum, family Myrtaceae) is the aromatic dried unopened flower bud of an evergreen tree.

Buds are hand-picked before opening and sundried; they owe their pungency to the essential oil eugenol.

It is not a fruit, stem or root, eliminating the other options.
