• B. \( \text{Geranial} \)
• C. \( \text{Ascaridole} \)
• D. \( \text{Menthol} \)

Hint:

Associate Chenopodium oil with its traditional use as a worm expellent. The presence of "scarid" in "ascaridole" might help you link it to its action against parasitic worms (ascarids).

Answer 1

The Correct Option is C

Chenopodium oil, derived from the plant *Chenopodium ambrosioides*, is well-known for its anthelmintic properties. The main active chemical constituent responsible for these properties is ascaridole, a naturally occurring monoterpene peroxide.
