Question

Match the correct combinations of answer : 
L - Energy Yielding : (I) Inorganic 
M - Body building : (II) Vitamin 
N - Protective : (III) Cellulose 
O - Roughage : (IV) Carbohydrate 
(V) Protein

Accepted Answer

Option 1 is the correct answer because it accurately matches each category with its appropriate description based on nutritional science:

1. **L - Energy Yielding: (IV) Carbohydrate**
   - Carbohydrates are the primary source of energy for the body. They are broken down into glucose, which is used by the body's cells for energy. This makes carbohydrates the most suitable match for the "Energy Yielding" category.

2. **M - Body building: (V) Protein**
   - Proteins are essential for the growth and repair of body tissues. They are the building blocks of muscles, skin, enzymes, and hormones, making them the ideal match for the "Body building" category.

3. **N - Protective: (II) Vitamin**
   - Vitamins play a crucial role in protecting the body against diseases and maintaining overall health. They support the immune system, help in the healing process, and are involved in various biochemical processes, making them the correct match for the "Protective" category.

4. **O - Roughage: (III) Cellulose**
   - Roughage, or dietary fiber, is primarily composed of cellulose. It aids in digestion by adding bulk to the stool and promoting regular bowel movements. This makes cellulose the appropriate match for the "Roughage" category.

Now, let's explain why the other options are incorrect:

- **Option 2: L-II, M-IV, N-I, O-V**
  - L-II: Vitamins are not primarily energy-yielding; carbohydrates are.
  - M-IV: Carbohydrates are not primarily body-building; proteins are.
  - N-I: Inorganic substances do not primarily serve a protective role; vitamins do.
  - O-V: Proteins are not roughage; cellulose is.

- **Option 3: L-III, M-V, N-I, O-II**
  - L-III: Cellulose is not energy-yielding; carbohydrates are.
  - M-V: This is correct, but the rest of the matches are incorrect.
  - N-I: Inorganic substances do not primarily serve a protective role; vitamins do.
  - O-II: Vitamins are not roughage; cellulose is.

- **Option 4: L-V, M-I, N-IV, O-III**
  - L-V: Proteins are not primarily energy-yielding; carbohydrates are.
  - M-I: Inorganic substances are not primarily body-building; proteins are.
  - N-IV: Carbohydrates are not primarily protective; vitamins are.
  - O-III: This is correct, but the rest of the matches are incorrect.

In conclusion, Option 1 is the only option that correctly matches each category with its appropriate description, making it the correct answer.
