The Correct Option is A
Solution and Explanation
Photorespiration is the light dependent process of oxygenation of ribulose biphosphate $(RuBP)$ and release of carbon dioxide by the photosynthetic organs of a plant. In the photorespiratory pathway, there is neither synthesis of sugars nor of $ATP$. Rather, it results in the release of $CO_{2}$ with the utilisation of $ATP$. Therefore, photorespiration is a wasteful process.

Processes Of Photosynthesis in Higher Plants:
Photosynthesis in higher plants involves the following processes:
- Light Reaction
- Dark Reaction
Light Reaction:
- This phenomenon occurs in the presence of light.
- The pigment absorbs light and produces energy in the form of ATP.
- The process involves- absorption of light, water splitting, the release of oxygen, and formation of ATP and NADPH.
Dark Reaction:
This process occurs in the absence of light in the stroma of the chloroplasts. The following cycles are involved in the process:
- Calvin Cycle (C3 Cycle)
- C4 Cycle (Hatch and Slack Pathway)
