Which one of the following is the most appropriate reason for aircraft being equipped with conducting tyres?
- A. They can transfer the charge accumulated on their surfaces during lightning.
- B. They can transfer the charge accumulated on their surfaces being rubbed by air particles. ✓
- C. They can transfer the charge accumulated on their surfaces due to inflight operation of several gadgets.
- D. For preventing sparks while they land on the ground.
Correct Answer: B. They can transfer the charge accumulated on their surfaces being rubbed by air particles.
