Answer:
(iv) Do not take shelter in a bus in the open.
Explanation:
As we know that buses are made up of metals from outside and hence when the lighting strikes the bus it would have no effect on inside , and it does not matter what lighting does to the outside part of the bus, but for extra knowledge the real reason is lighting is a static electricity and it is different from the electricity in our home and as far as I am concerned lighting has no effect on inside of a hollow closed conductor but has effect outside and hence car is a hollow conductor and closed too , so it would have no effect.
Hope it helps u :)
