Solution

The correct option is A
High atmospheric humidity

More moisture content in the atmosphere will reduce the rate of transpiration because the air is saturated with moisture. Good soil moisture will promote transpiration because there will be more water to evaporate. A high wind velocity will remove moisture from the vicinity of the stomata and promote transpiration. A dry environment will have less moisture and hence promote transpiration.
