Correct Answer: Option (C) — A is true but R is false

Concept & Option Breakdown

Standard Reference Verified

Assertion (A) is true: Fatty acids are essential components of a balanced human diet because they provide concentrated energy, build cell membrane structures, and act as precursors for vital hormones.

Reason (R) is false: The human body can synthesize many saturated and monounsaturated fatty acids via de novo lipogenesis. Only specific polyunsaturated fatty acids (essential fatty acids like linoleic acid and alpha-linolenic acid) cannot be synthesized and must come from food.

Elimination Heuristic & Exam Approach

The absolute quantifier 'cannot synthesize ANY fatty acids' makes Reason R factually incorrect.
