Which of the following connects the ocean floor level with the continental level ?

Answer: Option A

Continental slope connects the ocean floor level with the continental level. A continental shelf typically extends from the coast to depths of 100–200 metres (330–660 feet). It is gently inclined seaward at an average slope of about 0.1°. In nearly all instances, it ends at its seaward edge with an abrupt drop called the shelf break.
