what geological feature is located below an active volcano? a) branch pipes b) magma chamber c) subduction…

Brief Explanations:

Magma chambers are reservoirs of molten rock located beneath volcanoes. They supply the magma that erupts during volcanic activity. Branch pipes are part of the pathway for magma but not the main feature below. Subduction zones are tectonic - plate boundaries that can cause volcanic activity but are not directly below a single volcano. A caldera is a large depression formed after a volcanic eruption, not located below an active volcano during its normal activity.

Answer:

B. Magma chamber
