The correct answer is C) Pericycle.

Conducting tissues in plants are xylem and phloem, which are responsible for the transport of water, minerals, and food. Components of xylem include tracheids, vessels, xylem parenchyma, and xylem fibres. Components of phloem include sieve tubes, companion cells, phloem parenchyma, and phloem fibres. Fibres (both xylem and phloem fibres), Tracheids (xylem), and Sieve tubes (phloem) are all components of the conducting tissues. The pericycle is a layer of parenchyma cells located just inside the endodermis in the root and stem, surrounding the vascular tissue. It is involved in the formation of lateral roots and secondary growth (vascular cambium and cork cambium) but is not considered a part of the vascular or conducting tissue itself.

Vascular tissues are complex tissues composed of different cell types working together for transport. Xylem transports water and minerals from roots to leaves, while phloem transports sugars (food) from leaves to other parts of the plant. The pericycle is meristematic in some cases and plays a crucial role in the development of lateral organs and thickening growth, but its primary function is not conduction.
