Answer

Correct option: A.

Open stomata, dry atmosphere and moist soil.

(a) Open stomata, dry atmosphere and moist soil.
Explanation:
Transpiration pull is highest when stomata are open (allowing water vapour to escape), the atmosphere is dry (creating a greater gradient for water vapour to move from the plant to the air), and the soil is moist (ensuring adequate water supply for transpiration). These conditions collectively maximize the rate of transpiration.
