The correct Answer is:
A
Basalt is a common extrusive igneous (volcanic) rock formed from the rapid cooling of basaltic lava exposed at or very near the surface of a planet or Moon. It is an aphanitic igneous rock with less than 20% quartz and less than 10% feldspathoid by volume and where at least 65% of the feldspar is in the form of plagioclase.
