Water and minerals
B
Water only
C
Sugar
D
Food
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: -In plants, water and minerals are transported through xylem cells from soil to the leaves. The xylem cells of roots, stems and leaves are interconnected to form a conducting channel that reaches all parts of the plant body. The root cells take ions from the soil.

Detailed explanation-3: -The vascular tissue for the transport of water and nutrients in the plant is called the xylem [Fig. 11.7 (a)]. The xylem forms a continuous network of channels that connects roots to the leaves through the stem and branches and thus transports water to the entire plant [Fig.

Detailed explanation-4: -In plants, the water and minerals are first absorbed by the roots and then it is absorbed but the two vascular tissues namely xylem and phloem. After absorbing water and minerals, by these tissues then it is transported to all parts of plants such as stem, leaves, etc.
