|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.|
|Sachin Gowda said: (May 3, 2017)|
|Yes, A is correct. I agree.|

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

|Are you sure @Deepakra?|
|Bhargava said: (Jan 4, 2018)|
|You are right @Deepakra.|
|Biswadut said: (Jan 11, 2018)|
|Yes, at shallow depth (>2km) it's hypabyssal rock. And at greater depth it's plutonic rock.|
|Shivam Suhane said: (Mar 12, 2018)|
|Yes, the given answer is right.|
|Jyotsna said: (Apr 21, 2018)|
|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.|

|I think plutonic rock is the correct answer.|

|Cooling of magma = plutonic rock.
Pouring of magma = volcanic rock.
