The Correct Option is A
Solution and Explanation
Granite is an igneous rock.
Igneous rocks are formed by the cooling and solidification of magma or lava.
Igneous rocks are of two main types:
\[
\text{Intrusive igneous rocks}
\]
and
\[
\text{Extrusive igneous rocks}.
\]
Intrusive igneous rocks are formed when magma cools slowly inside the earth.
Because cooling takes place slowly, large crystals are formed.
Granite is formed by slow cooling of magma below the earth's surface.
Therefore, granite has a coarse-grained crystalline structure.
This makes granite an intrusive igneous rock.
Extrusive igneous rocks are formed when lava cools quickly on the earth's surface.
Basalt is a common example of extrusive igneous rock.
Hence, granite is an example of:
\[
\text{Intrusive igneous rock}.
\]
