Choose the incorrect statement with respect to photosynthesis.

Rubisco shows more affinity towards CO2 than O2 when their concentration is nearly equal. C3 plants have higher CO2 optima as 450μlL-1than C4 plants which have 360μlL -1. Bundle sheath of C4 plants is usually many layered around the vascular tissues but single layered in maize. In reduction stage of C3 cycle there is usage of 2 ATP and 2NADPH per CO2 molecule fixed.
