Match Column-I with Column-II.

Column-I Column-II (a) First product of CO2 fixation in C3 plants (i) Ribulose-1,5-bisphosphate (b) First product of CO2 fixation in C4 plants (ii) 3-phosphoglycerate (c) Enzyme for CO2 fixation in C3 pathway (iii) Oxaloacetic acid (d) Enzyme for CO2 fixation in C4 pathway (iv) RuBisCO

Choose the correct matching:

A

a-ii, b-iii, c-iv, d-i

B

a-i, b-ii, c-iv, d-iii

C

a-ii, b-i, c-iii, d-iv

D

a-iii, b-ii, c-iv, d-i

Option A

Detailed Explanation

In C3 plants, the first product of CO2 fixation is 3-phosphoglycerate (PGA), while in C4 plants, it is oxaloacetic acid (OAA). The enzyme responsible for CO2 fixation in C3 plants is RuBisCO, and in C4 plants, it is phosphoenolpyruvate carboxylase (not listed).
