None of the above

Detailed explanation-1: -The pathway of water from the soil through the plant to the atmosphere is best represented by: Root hairs-cortex-endodermis-vessel elements-intercellular spaces in mesophyll –stomata.
Detailed explanation-2: -Pathways of Water Movement. Water can move through the roots by three separate pathways: apoplast, symplast, and transmembrane (transcellular).
Detailed explanation-3: -This option represents the correct path of water movement from soil to xylem i.e., water is first absorbed from the soil by root hairs which then enters horizontally into the cortex, endodermis, pericycle, protoxylem, and metaxylem.
Detailed explanation-4: -Xylem Details– The xylem is probably the longest part of the pathway that water takes on its way to the leaves of a plant. It is also the path of least resistance, with about a billion times less resistance than cell to cell transport of water.
