Solution

The correct option is B phloem and xylem
Bulk flow or mass flow occurs due to positive hydrostatic pressure gradient in phloem and organic solutes are pushed. In xylem, water along with inorganic solutes are pulled by the negative hydrostatic pressure gradient created by the transpirational loss of water from the leaves.
