Correct:
B
Explanation
Clove (Syzygium aromaticum) essential oil's major and pharmacologically active constituent is eugenol. Review and analytical sources identify eugenol as the principal phenolic component responsible for clove’s medicinal properties, including analgesic and antiseptic actions [1]. Gas‑phase analyses report eugenol as the dominant volatile in clove oil (e.g., ≈76.8% of identified constituents in one profile), with other terpenes present only in much smaller amounts [2]. Further biochemical studies describe eugenol as a phenolic molecule with strong interactions with microbial enzymes, explaining much of clove oil’s bioactivity [3]. Therefore, among the options given, eugenol is the active component of oil of clove.
