What do vascular plants, like angiosperms, do to store sugars in their fruit pulp?
-they efficiently transport xylem sap throughout the plant body.
-they efficiently transport phloem sap throughout the plant body.
-they efficiently transpire and lose water at the leaf surface.

Option B, They efficiently transport phloem sap throughout the plant body.

Explanation:

In the process of photosynthesis, sugar is produced in the leaves and is then transported to locations where sugar is required for growth. Sugar is transported through the phloem in a process called translocation.  

The pressure flow model allows the movement of sugar through phloem sap. The water from xylem tissue moves into the phloem which creates high turgor pressure which cause bulk flow of sugar from its site of production (leaves) to site of requirement (pulp of fruits)

Thus, option B is correct.
