Conveys water and dissolved mineral from root to shoot.
A
Xylem
B
Phloem
C
Xylent
D
Epidermis
Explanation: 

Detailed explanation-1: -xylem, plant vascular tissue that conveys water and dissolved minerals from the roots to the rest of the plant and also provides physical support. Xylem tissue consists of a variety of specialized, water-conducting cells known as tracheary elements.

Detailed explanation-2: -The cohesion – tension theory of sap ascent explains how how water is pulled up from the roots to the top of the plant. Evaporation from mesophyll cells in the leaves produces a negative water potential gradient that causes water and minerals to move upwards from the roots through the xylem.

Detailed explanation-3: -The most distinctive xylem cells are the long tracheary elements that transport water.

Detailed explanation-4: -Most plants obtain the water and minerals they need through their roots. The path taken is: soil-> roots-> stems-> leaves. The minerals (e.g., K+, Ca2+) travel dissolved in the water (often accompanied by various organic molecules supplied by root cells).

Detailed explanation-5: -The type of vascular tissue that transports water and minerals in plants from roots to leaves is phloem.
