On a rainy evening storm grew loud and apace and dazzling streaks of light seen in the dark sky. Ananya was driving her car. At a turn, she saw a girl standing under a tree, trying to save herself from the rain. She stopped her car and called the girl to sit in the car. the girl who was deseparately looking for help took her assistance. Ananya a left the girl at her residence and during thier journey she explained the girl how lightning occurs and standing under a wet tree is very risky whereas sititng in a car is safe.

Why is it not safe to stand under a tree on a rainy day?
