Question

Which of the following examples of food under P, Q and R is correct?

P : Supplies materials for building cells

Q : Supplies a lot of energy

R : Supplies high dietary fibre

• A. P - Fish
  Q - Lettuce
  R - Palm oil
• B. P - Butter
  Q - Lettuce
  R - Fish
• C. P - Mutton
  Q - Butter
  R - Bean sprout
• D. P - Butter
  Q - Mutton
  R - Palm oil

Answer 1

The correct option is (C):

Explanation of the correct option:

1. Protein is the main structural component of cells and helps in building the body tissue, which is why P must be a protein-rich food source.
2. Fat is stored in the body as a source of energy which is consumed to increase absorption of more fat-soluble vitamins and hence Q will be food that must be rich in fat.
3. Roughage, also known as dietary fibre, plays an essential role in your overall health and better digestion of other components, even though it's mostly indigestible. Roughage belonging to R includes the green vegetables that are not able to be digested by humans.
   
4. In the given question P - Mutton (protein), Q - Butter (fats) and R - Bean sprouts (Roughage).
   

Explanation of the incorrect options:

Option A:

1. Fish is a good source of protein and can be correct for category 'P'.
2. Lettuce is a rich source of fibres, it is not rich in fat, so it does not fit the category 'Q'.
3. ​Palm oil is the source of fat not fibres, hence, not correct for category 'R'.

Option B:

1. Butter is a rich source of fat but not protein, hence, it does not fall in category 'P'.
2. Lettuce is a rich source of fibres, it is not rich in fat, so it does not fit the category 'Q'.
3. Fish is a rich source of proteins and not fibres, hence, it does not fall in the category 'R'.

Option D:

1. Butter is a rich source of fat but not protein, hence, it does not fall in category 'P'.
2. Mutton is a rich source of protein as compared to fats, hence, it does not fall in the category 'Q'.
3. ​Palm oil is the source of fat not fibres, hence, not correct for category 'R'.

Final Answer:

Among the following,

P - Mutton, Q - Butter, R - Bean sprout

are correct.
