Answer 1

The correct option is C

Excruive forms above Earth surface & intrusive forms below Earth surface

The intrusive igneous forms when magma hardens deep beneath the Earth's surface and the extrusive type is formed when lava hardens on the Earth's surface.

The magma is formed by the partial melting of the mantle and crust. Igneous form of rock is one of the three main types of rocks and is formed by the cooling and solidification of magma or lava.
