Which spice is derived from the bark of a tree?

Cinnamon is the correct answer because it is derived from the inner bark of trees belonging to the Cinnamomum genus. The process of harvesting cinnamon involves carefully peeling the bark from the tree, which is then dried and rolled into quills. This unique characteristic distinguishes cinnamon from other spices listed, such as clove, nutmeg, and ginger.

Clove comes from the flower buds of the clove tree, while nutmeg is obtained from the seed of the nutmeg fruit. Ginger, on the other hand, is the rhizome of the ginger plant. Each of these spices has different sources and methods of harvesting, making cinnamon noteworthy for its origin from tree bark.
