B Correct answer
Explanation

Gymnosperms typically lack vessels in their xylem tissue, relying primarily on tracheids for water and mineral transport. Tracheids are the fundamental water-conducting cells in gymnosperms, while vessels are a more advanced evolutionary development found predominantly in angiosperms. Xylem fibres and xylem parenchyma are present in gymnosperms as they serve structural and storage functions respectively.
