Step 1: Understanding lipids.
Lipids are a broad group of naturally occurring compounds that include fats, oils, waxes, and terpenes. Terpenes are hydrocarbons found in essential oils and are classified as lipids due to their solubility in organic solvents and role in biological processes.
Step 2: Analyzing the options.
(A) Cloroxyleneol: This is not a lipid but a disinfectant.
(B) Terpenes: This is the correct answer as terpenes are naturally occurring compounds that are part of lipids.
(C) BHA: BHA (Butylated HydroxyToluene) is an antioxidant, not a lipid.
(D) Novestrol: This is a synthetic compound used in pharmaceuticals, not a lipid.
Step 3: Conclusion.
The correct answer is (B) Terpenes.
