Solution

The correct option is B Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion.
Photorespiration is basically a wasteful process for plants. It occurs when the CO $_{2}$ levels inside a leaf become low. It takes place on hot dry days as stomata close to curtail transpiration. The low concentration of carbon dioxide leads to the attachment of oxygen with the RuBisCo and leads to the formation of phosphoglycolate which is converted into usable compound through glycolate mechanism.
Thus, option B is correct and other options are incorrect.
