Plants have two main transport tissues: Xylem carries water and minerals upward from roots, while Phloem carries prepared food (like sugars) from leaves to all other parts of the plant. Since the question is about food transport, the answer is Phloem, option (2).
PRO TIP
Re-check your working by substituting the answer back into the original question.
During a thunderstorm, the sound of thunder is heard 3 seconds after the lightning flash is seen. If the speed of sound in air is 340 m/s, how far away did the lightning strike? (Ignore the time taken by light.)
