• B. He should use white colored container
• C. Either of the containers will take same amount of time to boil the water
• D. Can’t be said

Answer 1

The correct option is A

He should use black colored container

We know that the temperature of a body rises with the absorption of heat energy and that a black body is a good absorber of heat energy. Hence, the rise in temperature of the body will be faster in the case of a black coloured container.
