A
water only
B
water and sucrose
C
water and mineral salts
D
mineral salts and sucrose
Explanation: 

Detailed explanation-1: -Xylem transports water, minerals, and nutrients from the soil to all the plant parts. There are two types of “transport” tissues in plants-xylem and phloem. Water and solutes are transported by the xylem from the roots to the leaves, and food is transported from the leaves to the rest of the plant by the phloem.

Detailed explanation-2: -The xylem transports water and minerals from the roots up the plant stem and into the leaves.

Detailed explanation-3: -The two primary vascular tissues are xylem, which transports water and dissolved minerals from the roots to the leaves, and phloem, which conducts food from the leaves to all parts of the plant.

Detailed explanation-4: -Xylem transports water and dissolved mineral salts from the roots to the rest of the plant.

Detailed explanation-5: -The mineral salts and water are specifically transported by xylem vessels, which originate from the roots and extend to the tips of the leaves. Food, on the other hand, is transported by phloem vessels which extend from leaves to different parts of the plant.
