Solution

The correct option is D IV, I, III, II
Enolase works on 2-phosphoglyceric acid (3C compound) to form phosphoenolpyruvate in the glycolysis pathway, aconitase on citric acid (6C compound), fumarase on fumaric acid (4C compound) and alcohol dehydrogenase on acetaldehyde (2C-compound). Thus, increasing order of these enzymes based on carbon number of their substrates is - IV, I, III, II.
