Solution

The correct option is C
1 and 3 only
Explanation:

Statement 1 and 3 are correct - Earth movements can cause rocks to be deeply buried or squeezed.
As a result, the rocks are heated and put under great pressure. Slate, Marble, Quartzite, Gneiss are examples of metamorphic rocks.

Statement 2 is incorrect – Their original character is greatly altered by the forces. They do not melt, but the minerals they contain are changed chemically, forming metamorphic rocks.
Sometimes, metamorphic rocks are formed when rocks are close to some molten magma, and so get heated up. When a metamorphic rock is formed under pressure, its crystals become arranged in layers.
