Detailed explanation-1: -so the correct answer is ‘Decrease in light intensity’.

Detailed explanation-2: -[D] As light intensity decreases, the rate of transpiration increases because stomata are open in the light.

Detailed explanation-3: -Increasing the light intensity to which a plant is exposed is predicted to cause an increase in the rate of transpiration. Increasing light exposure will cause more stomata to open in order to facilitate photosynthetic gas exchange.

Detailed explanation-4: -The rate of transpiration decreases with decrease in temperature and decrease in light intensity.

Detailed explanation-5: -Light has a direct influence on the opening and closing of stomata. The air gets humid when the light intensity decreases, and the rate of transpiration decreases. The transpiration rate decreases with the reduction of light intensity.
