C
a-i, b-iv, c-iii, d-ii
D
a-iii, b-i, c-ii, d-iv
Correct Answer
Option A
Detailed Explanation
The primary CO2 acceptor in the C4 pathway is oxaloacetic acid (OAA), formed from phosphoenol pyruvate (PEP) through the action of PEP carboxylase. The correct pairings highlight the roles of these components in the C4 pathway as described in the NCERT context.
