The most viscous magma type among the options you provided is rhyolitic magma. Rhyolitic magma has a high silica content, which contributes to its high viscosity compared to andesitic and basaltic magmas. Basaltic magma is the least viscous due to its lower silica content, while andesitic magma falls in between the two.
Choose the magma type which is most viscous:
andesitic
basaltic
rhyolitic
