Question

Match the nutrients given in List-I with the source in List-II:

List-I		List-II
1	Vitamin A	p	Bitter gourd
2	Single cell protein	q	Beans
3	Vitamin C	r	Carrots
4	Protein	s	Spirulina spp

Choose the correct option from the following :

• A. 1-p, 2-q, 3-r, 4-s
• B. 1-r, 2-s, 3-p, 4-q
• C. 1-p, 2-r, 3-s, 4-q
• D. 1-q, 2-s, 3-p, 4-r

Hint:

Balanced diets incorporating various sources ensure adequate nutrient intake.

Answer 1

The Correct Option is B

Matching nutrients with their sources:

1. Vitamin A - r. Carrots: Rich in beta-carotene (provitamin A).

2. Single cell protein - s. Spirulina spp: Cyanobacteria used as protein-rich food supplement.

3. Vitamin C - p. Bitter gourd: Excellent source of ascorbic acid.

4. Protein - q. Beans: Legumes are prime plant-based protein sources.

The correct matching is: (B) 1-r, 2-s, 3-p, 4-q

Other options are incorrect because: - (A) Incorrectly links vitamin A with bitter gourd - (C) Mismatches single cell protein with carrots - (D) Wrongly assigns vitamin A to beans

Answer 2

Vitamin A: Found in carrots, which are rich in beta-carotene, a precursor to vitamin A.

1 - r.

Single cell protein: Produced by microorganisms like Spirulina, a type of algae.

2 - s.

Vitamin C: Found in bitter gourd, a good source of ascorbic acid (vitamin C).

3 - p.

Protein: Found in beans, which are an excellent source of plant-based protein.

4 - q.

Thus, the correct matching is 1 - r, 2 - s, 3 - p, 4 - q, which corresponds to Option (B).
