Which outcome occurs when stratovolcano magma traps gases?

💡 Explanation

An explosive pyroclastic eruption occurs because gas pressure overcomes magma's tensile strength, causing violent Vesiculation. This fragmentation of magma creates pyroclastic flows. Therefore, choice A result's, rather than effusive eruptions, where gases escape passively.
