Answer: 2. It conducts water and minerals efficiently

Key idea: Heartwood is the old, central secondary xylem that has stopped conducting.

It is dead, heavily lignified, and filled with tannins, resins and oils, which make it dark and durable. The sapwood (outer, younger xylem) conducts water and minerals. So the wrong statement is (2).
