Solution
The correct option is A suction
A suction force created by transpiration leads to the ascent of sap. Evaporation from the leaves concentrates the cell sap and increases their osmotic pressure. This draws water from the cells at the lower levels in a sequential manner and finally favours absorption of water from the soil by the roots.
