Solution

The correct option is C
Oxygenation

Photorespiration is the uptake of $O_{2}$ instead of $C O_{2}$ in presence of light by green plants. In this reaction, RuBisCo binds to $O_{2}$ and produce one molecule of 3-PGA and one molecule of 2-phosphoglycolic acid through oxygenation. The equation is as follows -
