If a volcano’s magma is high in silica, the volcano will probably
a. erupt quietly.
b. remain dormant.
c. erupt explosively.
d. produce dark-colored lava.

The correct answer is - c. erupt explosively.

The type of eruptions of the volcanoes are determined by multiple factors, such as the silica content of magma, the type of gases, as well as what gases are present, water, etc.

The higher the amount of silica in the magma, the more explosive the eruption, and vice versa, the lower the silica content, the calmer the eruption.

When a magma is high in silica content, the magma is more viscous, thus denser, and because of that, the gases are trapped inside of it, so when the volcano erupts, it can be very violent as the gases trapped in the magma will be literary exploding.
