To answer the question regarding the type of rocks that form when magma solidifies, we can analyze the possible choices provided:

1. Crystalline: This is a term that often describes the structure of minerals or rocks, indicating a solid with a highly ordered arrangement of atoms, but it does not specify the process of formation.

2. Metamorphic: These are rocks that have transformed from an original rock type (igneous, sedimentary, or other metamorphic rocks) due to changes in temperature, pressure, or chemically active fluids.

3. Igneous: This term specifically refers to rocks that form through the cooling and solidification of magma or lava. They can be further classified into intrusive (plutonic) which forms below the Earth's surface, and extrusive (volcanic) which forms at the surface.

4. Magmatic: While this term is related to magma, it is not commonly used as a specific category of rock.

Final Answer

The correct answer is igneous rocks, as they form when magma solidifies.
