The correct answer is B) 1 and 2 only.

Statement 1 is correct: The ‘Ring of Fire’ is indeed known as the circum-Pacific belt, which is a major area in the basin of the Pacific Ocean where many earthquakes and volcanic eruptions occur.
Statement 2 is correct: It is an extremely active seismic zone due to the convergence and movement of tectonic plates, leading to frequent earthquakes.
Statement 3 is incorrect: The Ring of Fire is primarily characterized by *convergent* plate margins, specifically subduction zones, where one tectonic plate slides beneath another. While there are also areas of divergent and transform boundaries within or near the Pacific Basin, the dominant process driving the volcanism and seismicity of the Ring of Fire is subduction along convergent margins, not divergent boundaries (like mid-ocean ridges).

The Ring of Fire is a horseshoe-shaped zone that extends about 40,000 km (25,000 miles) and is associated with a continuous series of oceanic trenches, volcanic arcs, volcanic belts, and plate movements. It is home to about 75% of the world’s active volcanoes and 90% of the world’s earthquakes. Divergent plate margins, like the Mid-Atlantic Ridge, are areas where plates move apart, often leading to the formation of new crust and volcanism, but they are not the defining characteristic of the Ring of Fire.
