When a subduction zone is established under the edge of a continent, it can give rise to an accretionary wedge, a volcanic arc, and compressional features farther inland. This type of margin is known as an Andean margin, named after the Andes mountain range in South America where this type of margin is prominent. The other choices are not directly associated with subduction zones under continents - Aleutian is a subduction zone associated with an oceanic plate, Himalayan is a collisional margin, and passive margin lacks significant tectonic activity.
