Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Sometimes electric discharge can take place between the charged cloud and Earth. While passing over a tree or a tall building an opposite charge may be induced causing a lightning to strike the tree or a building and if the charge is large it may cause severe damage and may prove to be fatal. Thus, it is advised to stay away from tall buildings or tree during thunderstorms.
