Answer 1

Answer: (D)

Linoleic acid

Saturated monocarboxylic fatty acids have general formula $C_n{H}_{2n}{O}_2$

Palmitic acid is a saturated fatty acid with the formula $C_{16}{H}_{32}{O}_2$

Lauric acid is a saturated fatty acid with the formula $C_{12}{H}_{24}{O}_2$

Stearic acid is a saturated fatty acid with the formula $C_{18}{H}_{36}{O}_2$.

Linoleic acid is an unsaturated fatty acid with formula $C_{18}{H}_{32}{O}_2$
