Deandre Vaughan · Answer 1

The correct answer is option D.

Explanation:

Metamorphism : It defined as process in which change in composition and texture of the rock takes place without melting the rock. These changes in the rock are brought out by the effect of heat, pressure and introduction of an active chemical substance.

During this process crystal structure of the rock also changes although the rock remains in solid phase.
