• A. a-ii, b-iii, c-iv, d-i
• B. a-ii, b-iv, c-i, d-iii
• C. a-iii, b-ii, c-iv, d-i
• D. a-ii, b-iii, c-i, d-iv.

Answer 1

• Xylem- It consists of tracheids, vessels, xylem parenchyma and xylem fibres.
• Tracheids and vessels are hollow tube-like structures that help in conducting water and minerals. The xylem conducts only in one direction i.e vertically.
• The xylem parenchyma is responsible for storing the prepared food and assists in the conduction of water.
• Xylem fibres are supportive in function.

So, the correct answer is 'a-ii, b-iii, c-iv, d-i.'
