They carefully held a metal pan of ice cubes where water vapor was rising from the beaker and water drops began to form on the bottom of the metal pan.The water drops formed on the bottom of the pan because-

A the pan was made of metalB the water vapor cooledC the ice was a solidD the hot plate uses electricity
