1. Plutonic rock are those whose at depth more than 35 m.eg - granit,diorite.
2. Hypabsal rock are those at moderate depth less than 35 m. eg- dolerite.
3. Volcanic rocks are those which is at a surface of earth. eg- basalt.

I think Both A & D are true.

What about pegmatite? Give details about it.

Plutonic rock is the correct answer.

Platonic rocks are formed below the earth surface.

Igneous rocks are formed due to cooling and solidification of magma.

Igneous rocks have two types-.

1) Volcanic rocks which are formed on the earth surface.

2) Plutonic rocks which are formed at a considerable depth below the earth surface.

So I think plutonic is the very accurate answer.

Plutonic is the type of igneous rock formed under the surface.

Why not Volcanic rocks?

Vikrant said:   9 years ago
Sir, Igneous rocks and Volcanic rocks are same. Then why the answer is Plutonic rock.

The rocks made from the cooling and solidifying of molten rock (magma) are called igneous rocks and the two categories of igneous rocks - volcanic and plutonic rocks. Volcanic rocks found on earth surface whereas plutonic rocks found at considerable depth from earth's surface.
