Answer:
The correct answer is Extrusive igneous rocks.
Step-by-step explanation:
Extrusive igneous rocks also known as volcanic rocks form when magma reaches the Earth's surface in a volcano and cools rapidly.
This is the partial melting of the rocks inside the mantle and the crust.
They are smooth, fine-grained and crystalline. Its main effect is that magma cools much faster when it is outdoors or underwater, and this way, there is not much time left for crystal growth.
