Plutonic rocks are those rocks which form due to late crystallisation of magma as magma cools inside the earth's surface. Due to this the mineral crystals found in magma get enough time for crystallisation. These rocks contain big grains of their minerals. Granite is also a plutonic rock containing quartz, mica, feldspar which are clearly visible.

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 bodies.

Granite plutonuc (deep).

Dolerite hypabyssal rock (moderate).

Basalt volcanic (top surface).

Plutonic rock is making on earth surface & volcanic rock making in under the earth surface.

Eg of plutonic rock basalt & Granite.

I think the correct answer is plutonic (extrusive) basalt.

Granite is the example of volcanic (intrusive).

Plutonic = Granite.
Volcanic = Basalt.
Hypadyssal = Dolorite.
