Answer:
b. continental slope
Explanation:
It is a unit of undersea relief that is formed immediately after the continental shelf. It has a sedimentary origin and slopes to the ocean floor, reaching between 3,000 and 5,000 meters deep. The relief of the continental slope is not regular, and canyons and submerged valleys often occur. In this area we find marine remains and very fine clay. In this region we can also find isolated and arranged volcanoes, which give rise to the oceanic islands, for example, the islands of Hawaii.
