Solution

The correct option is B
Water continues to boil without paper cup getting burnt.

The water will boil in the paper cup, without the paper cup getting burnt. Here, the heat supplied to the paper cup is transferred to water by conduction. So, in the presence of water, the ignition temperature of paper is not reached. Hence, it does not burn while the water continues to boil.
