Igneous rock are of three types.

Plutonic: crystallization of magma at great depth, more than 35 m from earth's surface.

Hypabasal : at lower depth about 30m.

Volcanic: on or very less depth of earth's surface.

In geology, a pluton is a body of intrusive igneous rock (called a plutonic rock) that is crystallized from magma slowly cooling below the surface of the Earth. Plutons include batholiths, stocks, dikes, sills, laccoliths, lopoliths, and other igneous formations.

@Ranjit Ray.

A pegmatite is a holocrystalline, intrusive igneous rock composed of interlocking phaneritic crystals usually larger than 2.5 cm in size (1 inch); such rocks are referred to as pegmatitic.

Volcanic rocks or extrusive igneous rock is the correct answer.
