Solution
The correct option is B Transpirational pull
Transpiration is the loss of water in the form of vapour from aerial parts of the plant. It creates a suctional force, that pulls water from the roots to the leaves. This is known as transpiration pull.
Osmosis makes water move into the roots from soil. Root pressure can push this water only to small heights. This is why transpiration is required to pull water to larger heights.
