B. Northern Volcanic Zone of the Andes
The Northern Volcanic Zone of the Andes is a major Andean volcanic belt in Colombia and Ecuador characterized by active stratovolcanoes and frequent explosive eruptions driven by subduction of the Nazca Plate beneath South America.
C. Central Volcanic Zone of the Andes
The Central Volcanic Zone of the Andes is a major segment of the Andean volcanic chain characterized by numerous high stratovolcanoes and extensive volcanic plateaus spanning parts of Chile, Bolivia, Argentina, and Peru.
D. Garibaldi Volcanic Belt
The Garibaldi Volcanic Belt is a segment of the Cascade Volcanic Arc in southwestern British Columbia, Canada, characterized by a chain of volcanoes and volcanic features formed by subduction-related activity.
E. Andean Volcanic Belt
The Andean Volcanic Belt is a major volcanic chain along the Andes Mountains, formed by subduction of the Nazca and Antarctic plates beneath South America and hosting numerous active and dormant volcanoes.
F. None of above. chosen
G. Unsure - the case is ambiguous/there is not enough information to decide.
