What kind of rock is formed from molten material being cooled underground?

Sandstone
Siltstone
Basalt
Granite

The correct answer is: Basalt

Basalt is formed from molten material that cools underground, making it the best choice among the given options. Sandstone and siltstone are both formed from compacted sediment and would not be classified as rocks formed from molten material. Granite is formed from molten material that cools slowly beneath the Earth's surface, but it is not typically found underground, making it an incorrect choice.
