With which of the following oceans would you associate the ‘Ring of Fire’?

The correct option is Pacific.

The ‘Ring of Fire’ (also known as the Circum-Pacific Belt) is a path along the Pacific Ocean characterized by active volcanoes and frequent earthquakes.
It is a direct result of plate tectonics, specifically the movement, collision, and destruction of lithospheric plates under and around the Pacific Ocean.

Most of the Earth's volcanoes and earthquakes take place along the Ring of Fire due to the abundance of subduction zones, where heavier oceanic plates slide beneath lighter continental plates, creating intense pressure, melting rock into magma, and causing seismic activity.
