3. Metamorphic Rocks

Explanation:

1. 'Sedimentary Rocks':

These rocks are created by decomposition or weathering of the earth crust.

2. 'Igneous Rocks':

These rocks are formed because of 'high temperature', 'high pressure' and as well as high shearing stresses on existing sedimentary or igneous rocks.
