@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.

I think B is the correct answer.

Cooling of magma formed igneous rock. So I think answer D is correct.

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.

Volcanic is correct answer.

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.

I agree with you @Vikas.

The answer should be Hypabyssal because plutonic rocks are at high depth, Hypabyssal at considerable depth and exclusive are above the earth surface and these all are the type of the igneous rock.

The answer should be a igneous rock.

Because this rock will made from cooling of magma on earths surface.

Igneous rock is the correct answer.
