Answer:

The answers are B. Granite and D. Basalt.

Explanation:

Granite is an intrusive plutonic rock, which is formed from solidified magma in large masses inside the earth's crust. Magma cools slowly, allowing minerals to form large crystals, visible to the naked eye, as is the case with granite.

Basalt is an extrusive igneous rock, which is formed by the solidification of magma on the surface of the earth's crust, where cooling is much faster than in the case of intrusive rocks, so volcanic rocks are fine grain (invisible crystals with a naked eye), such as basalt.
