Correct answer
Explanation
Olympus Mons is the largest volcano in our solar system and is located on Mars. This shield volcano stands about 13.6 miles (22 km) high, nearly three times the height of Mount Everest. It covers an area roughly the size of France and formed over billions of years due to Mars' lack of plate tectonics.
