Baking is a method of cooking food that uses dry heat. A little or no fat is added in baked goods, but the cooking isn’t done in liquid fats.
Reheating cooked foods is bad as the food looses its nutrient value as well as its taste. Reheating also destroys many heat-sensitive vitamins, such as Vitamin C.

The volume of the stone is equal to the volume of the water increased in the measuring cylinder.
The volume of the stone is calculated from the formula Volume =Mass/Density.
In this case, the Mass = 12 g and Density = 3g cm^3
Volume = 12/3 = 4 cm^3
The actual volume of liquid in the measuring cylinder is
20cm^3
.
So, the increase in volume will show a new reading of
20cm3+4cm3=24cm^3
hence...answer is (B)
