Answer: c. rich in iron and magnesium

Explanation:

Basalt is an extrusive igneous rock that develops by the rapid cooling of the lava erupted after the volcanic eruption. This lava possibly consists of magnesium and iron which gets exposed to the terrestrial land. It is estimated that more than 90% of the rocks on the planet earth are basalt.
