The type of magma that builds up within a magma chamber determines the type of

a. magma that is created
b. volcano
c. eruption that will occur

Option C, Eruption that will occur

Explanation:

The constituents of magma especially the amount of gas in it is highly responsible for making a volcanic eruption exclusive.  

When a gas in entrapped with in a magma, a huge pressure is build on which keep on increasing with time and eventually it causes bursting of volcano thereby erupting magma. Also explosive eruptions causes  pyroclastic flows which destroys everything coming in their path.  

For example - Phreatomagmatic eruptions  

Thus, the constituents of magma are important to determine the type of eruption that will occur.
