Assertion: Photorespiration is a wasteful process where there is no synthesis of ATP energy.
Reason: RuBisCO is present in mesophyll cells of C4 plants hence they show more productivity.
If both assertion and reason are true and reason is the correct explanation of assertion.

If assertion is true but reason is false.
Photorespiration does not produce energy or reducing power. Rather it consumes energy.
In C4 plants, photorespiration, does not occur. Here, RuBisCO is located only in bundle sheath cells where photosynthetic release of oxygen does not occur. Bundle sheath cells have a high intracellular concentration of CO2 due to flow of C4 acids and their decarboxylation to release CO2.
Therefore, RuBisCO functions purely as carboxylase in C4 plants. They show high productivity and hence higher yield.
