D Correct answer
Explanation

Terpenes are composed of isoprene units (C5H8), which are five-carbon compounds that serve as building blocks. Monoterpenes have 2 isoprene units, sesquiterpenes have 3, and diterpenes have 4. Steroids are derived from terpenes but have a fused ring structure. Alkaloids contain nitrogen and peptones are protein derivatives.
