Step 1: Understanding the Concept:
Different food components have different energy values.
These are used in nutrition labeling.
Step 2: Key Formula or Approach:
No specific formula.
Need to know the energy values of food components.
Step 3: Detailed Explanation:
Ethyl alcohol: 7 kcal/g (A-III).
Dietary fibre: 2 kcal/g (B-I).
Organic acid: 3 kcal/g (C-IV).
Erythritol: 0 kcal/g (D-II).
Thus, A-III, B-I, C-IV, D-II is the correct matching.
Step 4: Final Answer:
The correct matching is A-III, B-I, C-IV, D-II.
Hence, the correct option is (A).
