9. Geranial is a lemon-scented natural aldehyde composed of 10 carbons. Based on its biosynthetic origin it is considered a:

		a. Monoterpene, when it is formed from geranyldiphosphate (GPP) by the action of geraniol synthase and geraniol dehydrogenase.
		b. Sesquiterpene, when it is formed from farnesyldiphosphate (FPP).
		c. Norisoprene (an apocarotenoid) when it is formed by degradation of tetraterpenes such as lycopene.
		d. Both A and C are correct.
		e. Due to convergent evolution it is unlikely that the same compound will be formed by two distinct metabolic processes.
