Solution

The correct option is B Entry of water into root hair and increase in volume of cell sap
Plants absorb water and nutrients through root hairs from the soil. When water moves from soil to root hairs then gradually volume of the cell increases and the water applies force on the walls of cells. As pressure increases turgor pressure also develops in epiblema cells of the root.
So, the correct answer is 'Entry of water into root hair and an increase in the volume of cell sap'.
