If the Assertion is correct but Reason is incorrect.

(C) The Assertion is correct because the presence of vessels in the xylem of angiosperms provides a more efficient pathway for water transport compared to tracheids alone. However,the Reason is incorrect. The conduction of water through xylem vessels is a passive process driven by transpiration pull (cohesion-tension theory),not an active process requiring energy from xylem parenchyma.
