Options
(i)
(ii)
(iii)
(iv)
Solution
(iv)
Explanation:
Do not take shelter in a bus in the open.
As we know, buses are made of metals from the outside, so when lighting strikes the bus, it has no effect on the inside, and it doesn't matter what lighting does to the outside part of the bus, but for extra knowledge, the real reason is lighting is static electricity, which is different from the electricity in our homes, lighting has no effect on the inside of a hollow closed conductor but has an effect on the outside.
