Detailed Solution

Assertion (A) is true. While C₄ plants have mechanisms to minimize photorespiration compared to C₃ plants, it makes photorespiration negligible.

Reason (R) is also true. C₄ plants have a mechanism known as carbon concentrating mechanisms (CCM), which increases the concentration of CO₂ in the Rubisco enzyme, minimizing the likelihood of oxygen binding to Rubisco and reducing photorespiration.

Both (A) and (R) are correct and (R) is the correct explanation of (A)
