Answer

Brief Explanation:

Igneous rocks are classified as intrusive or extrusive based on their formation location and pressure conditions. Intrusive rocks form deep in the Earth's crust under high - pressure conditions as magma cools slowly. Extrusive rocks form on the Earth's surface under low - pressure conditions as lava cools quickly.

Answer:

B. Intrusive rocks form under high pressure deep in Earth's crust, and extrusive rocks form under low pressure on the surface.
