b. This is an explosive eruption caused by high-viscosity magma.

Aimee Decker · Answer 2

a. This is a quiet eruption caused by low-viscosity magma.

I would say this is your answer because Non explosive eruptions are favored by low gas content and low viscosity magmas (basaltic to andesitic magmas). If the viscosity is low, non-explosive eruptions usually begin with fire fountains due to release of dissolved gases.

sorry if im wrong
