Question

Match the items of List-I with List-II and choose the correct option:
List-I (Food Group): (a) Protein, (b) Carbohydrates, (c) Fats, (d) Roughage
List-II (Functions): (i) Main sources of energy, (ii) Negligible energy source, (iii) Repair body cells, (iv) Transporting fat-soluble vitamins

• 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:

When matching, find the most certain pair first (like Carbohydrates-Energy) to eliminate incorrect options quickly.

Answer 1

The Correct Option is D

The question asks you to match the items from List-I, which lists different food groups, with List-II, which lists their corresponding functions. Let's analyze the items in both lists:

1. List-I (Food Group):
   • Protein (a): Known for being the building blocks of the body, proteins play a crucial role in the repair and maintenance of body tissues. Therefore, it is essential to match proteins with their primary function.
   • Carbohydrates (b): These are the main sources of energy for the body, providing fuel for daily activities.
   • Fats (c): Apart from being a source of energy, fats are crucial in transporting fat-soluble vitamins (A, D, E, and K) in the body.
   • Roughage (d): Also known as dietary fiber, roughage offers minimal energy but is vital for digestion and proper bowel movement.
2. List-II (Functions):
   • Main sources of energy (i): This function corresponds to carbohydrates, as they are the primary energy providers.
   • Negligible energy source (ii): This is a characteristic of roughage, which doesn't contribute significantly to energy but aids digestion.
   • Repair body cells (iii): This function closely aligns with proteins, which help in repairing and rebuilding body cells.
   • Transporting fat-soluble vitamins (iv): This function corresponds to fats, which help in the transport and absorption of vitamins.

Now, let's match the items correctly based on our analysis:

• (a) Protein matches with (iii) Repair body cells.
• (b) Carbohydrates match with (i) Main sources of energy.
• (c) Fats match with (iv) Transporting fat-soluble vitamins.
• (d) Roughage matches with (ii) Negligible energy source.

Therefore, the correct option is (a)-(iii), (b)-(i), (c)-(iv), (d)-(ii).

Answer 2

A quicker strategy for a matching question like this, once you're confident in one pairing, is to use it to eliminate options rather than working out all four matches from scratch. Here, Protein's pairing settles it quickly.

1. (a)-(i), (b)-(ii), (c)-(iii), (d)-(iv): Here Protein is matched to (i), main source of energy, but protein is not the body's primary fuel source, carbohydrates hold that role, so this option can be eliminated immediately on the very first pairing.
2. (a)-(iv), (b)-(iii), (c)-(i), (d)-(ii): Here Protein is matched to (iv), transporting fat-soluble vitamins, but that is specifically a function of dietary fat, not protein, so this option fails on its first pairing as well.
3. (a)-(iii), (b)-(iv), (c)-(i), (d)-(ii): Protein-(iii) is correct here, repairing body cells is exactly protein's role, but Carbohydrates is matched to (iv), vitamin transport, which belongs to fats instead, so this option fails on its second pairing.
4. (a)-(iii), (b)-(i), (c)-(iv), (d)-(ii): Protein-(iii) is correct, and checking onward, Carbohydrates-(i) is correct (energy source), Fats-(iv) is correct (vitamin transport), and Roughage-(ii) is correct (negligible energy), so every pairing in this option holds up.

Starting from the one pairing everyone should know cold, that protein repairs cells rather than supplying primary energy, immediately eliminates two of the four options, and checking the remaining pairings confirms only one option survives completely intact.

Therefore, the correct answer is (a)-(iii), (b)-(i), (c)-(iv), (d)-(ii).
