Solution

The correct option is B Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion
Stomata are minute pores situated on the leaf surfaces. They are surrounded by 2 guard cells. When these guard cells are filled with water, the stomata open up and the process of transpiration takes place. These stomatal pores open in light and close in dark. Furthermore, the wavelength of specific radiation also enhances the healing effect of light.
So, both the given statements are correct. But the reason is not true for the assertion.
So, option B is the correct answer.
