Answer:
B. intrusion of magma into fractions
Explanation:
A pluton is a type of rock that is formed when magma cools and solidifies underground, they are an intrusive igneous rock (forced into other layers of rock), usually in cracks. The three main types of pluton are bysmalith (cylindrical), lopolith (mushroom-shaped), and laccolith (blister-shaped).
Because magma is under high pressure and takes a long time to cool, it allows time for the formation of large crystals. Therefore, plutonic rocks have coarse-grained crystals that come in many different colors and sizes. A good example is granite.
<em>Considering this information we can conclude that pluton is not manmade rock, they come in different sizes (not only large) so the correct answer is B. intrusion of magma into fractions. </em>
I hope you find this information useful and interesting! Good luck!
