Study the following type of secondary metabolite and select the correct option. i) Terpenes: Made from mevalonic acid that is composed mainly of carbon and hydrogen. ii) Phenolics: Extremely diverse class may also contain sulphur.

Step-by-step solution

Terpenes are a large and diverse class of organic compounds, produced by a variety of plants, particularly conifers. They are derived from the mevalonic acid pathway and are composed mainly of carbon and hydrogen (isoprene units). Thus, statement i is correct. Phenolics are an extremely diverse class of secondary metabolites that contain a hydroxyl group bonded directly to an aromatic hydrocarbon group. They are composed of carbon, hydrogen, and oxygen, but do not contain sulphur. Sulphur-containing secondary metab
