Solution

The correct option is C Higher concentrations of $N O_{2}$ is good for the leaves of plants and the rate of photosynthesis.
Option (a) and (b) are correct but option (c) is not true because higher concentrations of $N O_{2}$ damage the leaves of plants and retard the rate of photosynthesis.
