Answer: Option (d) is the correct answer.
Explanation:
During a lightening strike, when an individual is in a house 8 miles away then he will be safe.
This is because house is a closed shelter so lightening cannot enter inside the house unless and until the windows or doors are open.
Whereas a tent cannot be safe during lightening strike as tent is made up of cloth or light weight material. Hence, it does not provide any protection during lightening strike.
On the other hand, a person standing 8 miles away or a person on a bike 8 miles away is not safe as both bike and ground are conducting in nature. So, it may lead to death if lightening strikes on it.
