The correct answer is - Rhyolitic.
The rhyolitic magma is the type of magma that causes most of the explosive eruptions of the volcanoes around the world. This magma is causing explosive eruptions because of the high content of silica and gasses in the magma. The magma is denser because of the high silica content. The gasses are getting trapped into the dense magma, and when they finally mange to get out of it, because of the enormous pressure, they tend to explode, thus the explosive eruptions.
