Which is an igneous rock formed by cooling lava?

Explanation:
Basalt is formed when lava erupts onto the surface and cools rapidly, producing a fine-grained, dark igneous rock. That quick cooling at the surface gives basalt its characteristic texture and composition. The other options aren’t rocks formed by cooling lava: a basic volcano is a landform, while bioaccumulation and biogas describe processes and fuel, not rocks.
