Redwood trees are among the tallest trees in the world, reaching more than 110 meters (m) in height. Which property of water allows it to
travel such large distances from the roots of the redwood tree to the
leaves?
A. molecular expansion
B. low molecular density
C. versatility as a solvent
D. cohesion and adhesion

D. cohesion and adhesion

Explanation:

Cohesion is the ability of a substance to attract its molecules to one another whereas adhesion refers to the attraction of the molecules of a substance to other substances.

Water molecules are attracted to each other by cohesive forces due to hydrogen bonding, which causes the molecules of water to tend to stick to one another resisting to be ruptured. This is seen in the surface tension of water.

Also, water molecules are attracted to other molecules by adhesive forces. This is seen in the capillarity of water where it travels up a thin tube due to attraction of water molecules to the walls of the tube.

Cohesive and adhesive forces work together and enables the transport of water from the roots to the leaves in plants by transpiration pull. This pull is due to the ability of water molecules being evaporated on the surface of the plant to remain in contact with water molecules below them by cohesion, and then travelling up the tree by adhesion to the walls of the xylem of the plant which acts as capillary tubes.
