Solution

The correct option is A Auxin
Auxin is synthesized at the shoot and root tips and is responsible for tropic growth in plants. This hormone controls phototropism as well as geotropism. Auxin enters the root cells and makes it more elastic. As a result the absorption of water by root increases. Thus the correct answer is option A.
