Answer

Brief Explanations:

Low - viscosity magma flows easily and allows gas to escape gradually, resulting in a weak eruption. Magma that cannot flow easily (high viscosity) often leads to explosive eruptions as gas builds up. Magma with high gas content and high silica content (which increases viscosity) is more likely to cause explosive eruptions.

Answer:

C. Magma with low viscosity
