Explanation:

Continental margin is said to be the connection between the oceanic crust and the continental crust.  Continental margin separates the sea floor from the continental crust.This margin is usually the shallow region that approaches the continental crust.

All the following options are parts of a continental margin except  Fracture zone which is a weakness in the earth crust that cut across the mid oceanic ridges.

Continental shelf extends from the edge of the continent towards the sea floor and are shallow in nature. This portion of the continental margin transition from the continent to the sea. They are gently inclined and typically flat.

Continental slope extends from the continental shelf to the depth of the oceanic floor. continental slopes are relatively steep.

Continental rise exist at the foot of the continental slope and they are located between the continental slope and the abyssal plain(A flat plain at the base of continental rise).

Submarine canyon are valleys that runs across continental shelf down the continental slopes.
