The correct answer is - B. Rhyolitic.

The rhyolitic magma has a trademark signature to be the magma type that causes the most catastrophic, powerful, explosive volcanic eruptions. This is due to the composition of the magma. This type of magma is very high in silica content, which in turn makes it very viscous, and because it is very viscous, the high amount of gasses that it contains remain trapped in it, the pressure is building up inside of it, so when it reaches the surface it is highly explosive.
