Hint:

The Krebs cycle involves organic acids of different carbon numbers, playing a key role in cellular respiration.

Answer 1

The Correct Option is D

Step 1: Understanding Carbon Counting in Organic Acids
- $\alpha$-Ketoglutaric acid → 5 carbons.
- Succinic acid → 4 carbons.
- Citric acid → 6 carbons.
- Acetyl group of Acetyl CoA → 2 carbons.
Step 2: Matching Correctly
The correct matching is A-IV, B-II, C-I, D-III.
