Solution
The correct option is C sieve tubes
Companion cells are specialised parenchymatous cells that are closely associated with the sieve tube elements in the phloem. The companion cells are non-conducting cells. Its nucleus controls the activity of the sieve tube element as mature sieve tube elements lack nucleus. Sieve tubes are the primary conducting cells of phloem. They are elongated living cells that are arranged longitudinally. Their end walls are perforated. They are present only in angiosperms.
Xylem is a conducting tissue for water and minerals. It is a complex tissue and is made up of four different cell types - tracheids, vessel elements, xylem parenchyma and xylem fibres.
Cambium is a meristematic tissue that gives rise to the vascular tissues - xylem and phloem.
Collenchyma is a simple permanent tissue which provides support, mechanical strength and flexibility to plant parts.
