Answer:
Option (D)
Explanation:
Rocks that are formed from the cooling and crystallization of magma are known as the igneous rocks. These rocks are formed either on the surface or under the earth's surface.
When magma comes out to the surface, then the lava solidifies and forms extrusive igneous rocks. For example, basalt and rhyolite.
On the other hand, when magma crystallizes below the earth's surface due to the lowering of temperature, then it forms intrusive igneous rocks. For example, granite and gabbro.
Thus, the correct answer is option (D).
