Most of the heat generated during the processes like contact metamorphism is supplied by a nearby mass of magma. Therefore, the option B holds true.

What is the significance of contact metamorphism?

Contact metamorphism is a naturally occurring process wherein the temperature of a few rocks present near magma get extremely hot in their temperature. It often leads to formation of limestone from the rocks present on the surface of the Earth.

Contact metamorphism, or simply thermal metamorphism, is a process that takes place when rocks on the surface of the Earth get heated up due to the igneous intrusions of hot magma present nearby such rocks. Magma is present in masses, and not just in singular numbers.

Therefore, the option B holds true regarding the significance of contact metamorphism.
