a. Ring of Fire***
b. Milford Track
c. Great Barrier Reef
Right.
The correct answer is a. Ring of Fire.
To arrive at this answer, we need to understand what the Ring of Fire is and its relevance to volcanoes.
The Ring of Fire is a major area in the basin of the Pacific Ocean where a large number of earthquakes and volcanic eruptions occur. It forms a 40,000 kilometer (25,000 mile) horseshoe shape that's associated with a nearly continuous series of oceanic trenches, volcanic arcs, volcanic belts, and plate movements. The Ring of Fire is home to about 75 percent of the world's active volcanoes.
By understanding the characteristics and distribution of volcanoes around the world, we can determine that the majority of them are found in the Ring of Fire. Therefore, the correct answer to the question is a. Ring of Fire.
