Question

Given below are the food groups in List-I with their functions in List-II.

• A. (a)-(i), (b)-(ii), (c)-(iii), (d)-(iv)
• B. (a)-(iv), (b)-(iii), (c)-(i), (d)-(ii)
• C. (a)-(iii), (b)-(iv), (c)-(i), (d)-(ii)
• D. (a)-(iii), (b)-(i), (c)-(iv), (d)-(ii)

Hint:

To solve matching questions quickly, find the most definite pair first. For example, Protein $\rightarrow$ Repairing cells (iii) and Carbohydrates $\rightarrow$ Main Energy (i) quickly isolates option (D).

Answer 1

The Correct Option is D

Step 1: Analyzing the Biological Function of Each Dietary Component:

• (a) Protein: Serves as the primary structural block of cellular tissue, essential for growth and repairing body cells $\rightarrow$ (iii).
• (b) Carbohydrates: Act as the body's primary, readily available metabolic substrate and main source of energy $\rightarrow$ (i).
• (c) Fats: Concentrated energy reserves that dissolve and transport essential fat-soluble vitamins ($A, D, E, K$) $\rightarrow$ (iv).
• (d) Roughage: Non-digestible dietary fiber that adds bulk to feces and assists digestion, contributing negligible caloric energy $\rightarrow$ (ii).

Step 2: Compiling the Ordered Vector:
Matching these pairs gives: (a)-(iii), (b)-(i), (c)-(iv), (d)-(ii). This corresponds exactly to option (D).
