Correct option is A
The correct answer is (a) Most fatty acids have carboxyl group at one end and methyl group at the other end
Explanation:
• Fatty acids are long hydrocarbon chains with a terminal carboxyl (–COOH) group and an opposite methyl (–CH₃) (omega) end.
• Saturated fatty acids have no C=C double bonds.
• Monounsaturated have one double bond (therefore fewer H than saturated).
• Statements (b), (c), (d) are incorrect.

Information Booster:
• Many naturally occurring fatty acids have even-numbered carbon chains.
• Nomenclature: α (carboxyl end) and ω (methyl end).
Additional Knowledge:
(b)/(c) — incorrect statements about double-bond counts.
(d) — monounsaturated do not carry maximum hydrogens; saturated do.
