(B) The exudation of xylem sap from the cut end of a stem is a phenomenon known as bleeding or guttation,which is primarily caused by $root$ pressure.$Root$ pressure is the positive pressure that develops in the roots of plants due to the active absorption of mineral ions from the soil,which leads to water following by osmosis.This pressure is sufficient to push water and dissolved solutes up to small heights in the stem,especially when transpiration is low,such as at night or early morning.

Exudation of xylem sap at the cut end of stem is due to . . . . . . pressure.
