The correct answer is option 1, Dolomite. Dolomite is not an igneous rock. Igneous rocks are formed from the cooling and solidification of magma or lava, while dolomite is a sedimentary rock composed of calcium magnesium carbonate.
Option 2, Granite, is an example of an igneous rock. It is formed from the slow cooling and solidification of magma deep beneath the Earth`s surface. Granite is known for its coarse-grained texture and mineral composition.
Option 3, Basalt, is another example of an igneous rock. It is formed from the rapid cooling and solidification of lava on the Earth`s surface. Basalt is characterized by its fine-grained texture and dark color.
Option 4, Gabbro, is also an igneous rock. It is similar in composition to basalt but with larger mineral grains due to slower cooling and solidification. Gabbro is typically found in the deeper layers of the Earth`s crust.
