Clove: which of the following was listed as a constituent?

Explanation:
Clove essential oil is dominated by phenolic compounds, with eugenol standing out as the major constituent. Eugenol has a hydroxyl group directly attached to an aromatic ring, which classifies it as a phenol. This set apart from the other options: an alcohol would have an OH on a non-aromatic carbon, a phenolic ether would feature an ether linkage on the aromatic ring without the free OH, and an ester contains a carbonyl connected to oxygen. While other constituents like eugenol acetate (an ester) can be present in small amounts, the listed major constituent is a phenol.
