A	$4C$ compound	1	Acetyl Co-A
B	$2C$ compound	2	Pyruvate
C	$5C$ compound	3	Citric acid
D	$3C$ compound	4	$\alpha -$ ketoglutaic acid
		5	Malic acid

• A. A-2, B-5, C-3, D-1
• B. A-3, B-1, C-4, D-2
• C. A-5, B-1, C-4, D-2
• D. A-5, B-3, C-1, D-2

Answer 1

The correct option is C A-5, B-1, C-4, D-2

A. Malic acid is a 4C compound and has the formula C${}_4$H${}_6$O${}_5$.

B. Acetyl Co-A is a 2C compound and consists of two carbon units joined to Co-A.

C. α-ketoglutaric acid is a derivative of glutaric acid and is a 5C compound.

D. Pyruvate is a 3C compound and has the formula C${}_3$H${}_4$O${}_3$.

So, the correct answer is 'A-5, B-1, C-4, D-2'.
