The ocean rim which is called the "ring of fire" because of the several volcanoes and other tectonic activities present there is <span> Pacific ocean. The answer to your question is B. </span>I hope this is the answer that you are looking for and it comes to your help.
The "Ring of Fire" is the oceanic rim formed along the boundary of the pacific ocean where a high number of earthquakes and eruptions of volcanoes take place. The shape of this ring resembles a horse-shoe and the areas that are located in and around this location are prone to the significant number of earthquakes and volcanism. This ring is about 40,000 km long and has formed due to the subduction of the Pacific plate under the Indo-Australian plate, North American and South American plate. It is a convergent plate boundary marked by the presence of deep-sea trenches and volcanic island arcs.
Due to this continuous plate collision along this boundary, tectonic activities are very frequent.
Since it has 4 protons, it must have an atomic number of 4. (That makes it beryllium.) Since it has a 4 protons and 5 neutrons, it has a mass number of 9.
