The correct option is (D) all of the above. Volcanic activity, earthquakes, plate interactions all occur at the continental margin in the Pacific Ocean.
Further Explanation:
Continental margins are generally ‘narrow’ and have ‘steep’ continental slopes and they are either poorly developed ‘continental rises’ or none at all. They are found on the edges of ‘tectonic plates’ like around the edge of the Pacific Ocean. The “continental margin” is one of the ocean floor’s major zones. There are total of three major zones, the other two being mid-ocean ridges and deep-ocean basins.
Continental margins are the shallow areas that are found near to the continent. The “continental margin” comprises of three different characteristics: the continental slope, the continental shelf, and the continental slope. There are two kinds of continental margins, namely active margin and passive margin.
Active margins are associated with “lithospheric plate” boundaries. These margins can be transforming or convergent margins and they are also places of “high tectonic activity”, including earthquakes and volcanoes. Whereas, passive margins are located inside of lithospheric plates which are away from the “plate boundaries” and lack major “tectonic activity”.
