(A) When the relative humidity of the atmosphere is $100\%$,the water potential gradient between the leaf interior and the atmosphere becomes zero.Since transpiration is the loss of water in the form of water vapor from the aerial parts of the plant,it depends on the vapor pressure deficit between the leaf and the surrounding air.At $100\%$ relative humidity,the air is saturated with water vapor,meaning there is no driving force for water loss.However,stomata generally remain open during the day to facilitate gas exchange ($CO_2$ uptake for photosynthesis),even if transpiration is negligible or absent due to the saturated atmosphere.

When the relative humidity of the atmosphere is $100\%$ during the daytime,the stomata shall:
