Answer: Option B
Solution:
Lava solidifies to form Basalt. Basalt is an extrusive igneous rock which is formed by rapid cooling of basaltic lava which is exposed near the surface of Earth. Basalt is a fine-grained, hard rock which forms when bits of lava shoot out of volcanoes. It forms when lava reaches the Earth's surface near an active volcano.
