• B. a-4, b-3, c-2, d-1
• C. a-3, b-2, c-1, d-4
• D. a-2, b-1, c-4, d-3
• E. a-1, b-2, c-3, d-4

Answer 1

The correct option is A a-3, b-4, c-2, d-1

Xylem vessels - The hollow vessel elements are joined in files and their adjoining end walls are perforated (perforation plates). Xylem tracheids - They are elongated tube like cells with tapering ends and chisel like in appearance. Xylem fibre - The fibers of xylem have thick walls and obliterated central lumen. Xylem parenchyma - The parenchyma cells function to store metabolites, or function in secretion (resin ducts and laticifers).

So, the correct answer is 'a-3, b-4, c-2, d-1.'
