Consider the following:

Basalt

Granite

Marble

Which of the above is/are igneous rocks?

Question

Basalt is an igneous rock formed from the rapid cooling of lava at the Earth's surface, often found in volcanic regions. It is dark in color and has a fine-grained texture.
Granite, also an igneous rock, is formed from the slow crystallization of magma beneath the Earth's surface, characterized by its coarse-grained texture and light color.
Marble, however, is a metamorphic rock formed from the recrystallization of limestone under heat and pressure, making it distinct from the igneous category.
