• Xylem fibres only provide mechanical support. They have no role in conduction of water and minerals . Hence, option (a), (b) are wrong .
• Sieve tubes are component of Phloem tissue . They are very long and have a tube like structure . It's function is mainly carried out by nucleus of companion cells as they are related by Ontogeny . Hence, option (d) and (e) are wrong.
