The correct option is D Trachea
A vessel element or vessel member (trachea) is one of the cell types found in xylem, the water conducting tissue of plants. The lumen of vessels is wide than tracheids and end wall is perforated (Transverse septum is absent between two vessel elements. If present then porous). Thus vessels are more capable of conduction of water than tracheids. So, the correct option is Trachea.
