Correct option is B
Explanation-
A. Xylem tracheids are highly elongated tapered cells that conduct water - CORRECT
Tracheids are elongated, spindle-shaped (tapered) cells found in the xylem of vascular plants. They are dead at maturity, have thick lignified walls, and conduct water and minerals through pits.
B. Xylem vessel elements are less elongated and narrower than tracheids - INCORRECT
Xylem vessel elements are actually shorter and wider (not narrower) than tracheids. They join end-to-end to form vessels, allowing more efficient water transport. So, this statement is partially correct (less elongated) but incorrect in saying “narrower”.
C. Angiosperms may have both tracheids and vessel elements - CORRECT
Angiosperms (flowering plants) typically possess both - Tracheids and Vessel elements. This dual presence allows more efficient water conduction and support.
D. Vessel elements are the only tracheary elements in almost all gymnosperms - INCORRECT
Gymnosperms (e.g., conifers) primarily have tracheids, not vessel elements. Most gymnosperms lack vessel elements, except for a few like Gnetophytes (e.g., Gnetum). Hence, this statement is factually incorrect.
Final Answer:
Only Statements A and C are correct.
So, the correct choice is: Option b – A and C only
