Solution

The correct option is B Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion.
Xylem, which are the tissues responsible for transportation of water and minerals in the plant are made up of tracheids and vessels elements. The tracheids are elongated cells with lignified walls. The vessels, on the other hand, are dead cells with large perforations, making them more efficient in transporting water and minerals.
So, the correct answer is option B.
