A
Cambium layer
B
Heartwood
C
Inner Bark
D
Sapwood
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: -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-3: -Xylem transport occurs through the dead and hollow xylem vessels that belong to the apoplastic space. In addition to inorganic salts, organic nutrients, such as amino acids, sugars, and organic acids are translocated through the xylem from roots to aerial organs [2–4].

Detailed explanation-4: -The xylem distributes water and dissolved minerals upward through the plant, from the roots to the leaves. The phloem carries food downward from the leaves to the roots. Xylem cells constitute the major part of a mature woody stem or root.
