   Answer: (4) Basalt

   సమాధానం: (4) బసాల్ట్

   Extrusive (volcanic) igneous rocks form when lava cools quickly on the Earth's surface, and basalt is the classic example; the Deccan Traps are made of it. Coal is a sedimentary rock, graphite is a form of carbon found in metamorphic rocks, and fossils are preserved remains of organisms, not a rock type.
