Hint We have a sphere, a cube, and a circular plate. All are made of the same material and have the same mass. We have to find which of them will cool faster when they are heated to the same high temperature. The cooling will be depending on the shape of the material.

Complete Step by step solution
From the given shapes, all of them have the same mass. The circular plate will be having the largest surface area out of the three. This will help the plate to cool down faster. Out of the three, the sphere will be the shape having the minimum surface area for a given volume. Hence the sphere will be cooling down the slowest. Therefore, we can say that the plate will cool the fastest and the sphere the slowest.

The answer is: Option (C): The plate will cool the fastest and the sphere the slowest.
