Solution
No, we should not carry an umbrella in a thunderstorm. During thunderstorms, which are accompanied by lightning, electric discharge from the clouds can travel through the metallic rod of the umbrella. This may give an electric shock to the person who is carrying it. Hence, it is not safe to carry an umbrella during lightning.
