Explanation:

Only statement 3rd is correct.
The Pacific ‘Ring of Fire’ or Pacific rim, or the Circum-Pacific Belt, is an area along the Pacific Ocean that is characterised by active volcanoes and frequent earthquakes. 

• It is home to about 75 per cent of the world’s volcanoes – more than 450 volcanoes. Also, about 90 per cent of the world’s earthquakes occur here.

The volcanic island arcs are parallel to, and always landward of, the trenches. 

• For example, the island arc associated with the Aleutian Trench is represented by the long chain of volcanoes that make up the Aleutian Islands. 

The area is along several tectonic plates including the Pacific plate, Philippine Plate, Juan de Fuca plate, Cocos plate, Nazca plate, and North American plate. 

• The movement of these plates or tectonic activity makes the area witness abundant earthquakes and tsunamis every year.

Hence option 3rd is correct.
