Solution : The correct option is Two .
Depending on how they were formed, igneous rocks can be divided into two primary categories:
- Plutonic intrusive igneous rocks: Beneath the Earth's surface, molten lava cools and solidifies gradually to generate these rocks. Examples consist of gabbro, diorite and granite.
- Volcanic extrusive igneous rocks: Lava cools and solidifies quickly, forming these rocks on the surface of the Earth. Pumice, andesite and basalt are a few examples.
