Answer 2

The rock which is harder than its original constituent is: (c) Metamorphic rock.

Explanation for the answer:

• Rocks is a solid mass which is made up of one or more minerals which are combined together by chemical bonds.
• Metamorphic rocks are mostly harder than the sedimentary rocks.
• They are hard and sometimes even harder than igneous rocks.
• They constitute the roots of many mountain chains and are also exposed to the surface even after the softer outer layers of rocks are eroded away.
• Hence, the correct answer among all the options is option (c) Metamorphic rock.
