The correct matching of the volcanic mountains with their respective countries is as follows:

• Mount Rainier: An active stratovolcano located in the Cascade Range of Washington state, U.S.A. (A-4).
• Mount Etna: Located on the east coast of Sicily, Italy, it is one of the world's most active volcanoes and the highest peak in Italy south of the Alps (B-1).
• Mount Pericutine (Parícutin): A cinder cone volcano in the state of Michoacán, Mexico. It is unique as its entire lifecycle (birth to extinction) was observed by scientists starting in 1943 (C-2).
