Model Answer

(A) Both Assertion (A) and Reason (R) are true and Reason (R) is the correct explanation of the Assertion (A).

Explanation

The textbook directly states that vegetable oils have long unsaturated carbon chains, and oils containing unsaturated fatty acids are healthier than saturated animal fats. Thus, R correctly explains A. Source: Chapter 4, Section 4.3.3.
