Plutonic rock is correct.

Yes, Plutonic rocks is correct.

A subvolcanic rock, also known as a hypabyssal rock, is an intrusive igneous rock that is emplaced at medium to shallow depths within the crust, and has intermediate grain size and often porphyritic texture between that of volcanic and plutonic rocks.

TYPE OF IGNEOUS ROCK.
On the surface -- VOLCANIC.
At a Shallow depth -- HYPABYSSAL.
At a GREAT DEPTH -- PLUTONIC.

Are you sure @Deepakra?

You are right @Deepakra.

Yes, at shallow depth (>2km) it's hypabyssal rock. And at greater depth it's plutonic rock.

Shivam Suhane said:   7 years ago
Yes, the given answer is right.

Extrusive igneous rocks, also known as volcanic rocks, are formed at the crust's surface as a result of the partial melting of rocks within the mantle and crust. Extrusive igneous rocks cool and solidify quicker than intrusive igneous rocks. They are formed by the cooling of molten magma on the earth's surface.
