The correct CHOICE is (C) Train suspension

Easiest explanation: FOUR-bar linkage, also called a four-bar, is the simplest MOVABLE closed chain linkage. It consists of four bodies, called bars or links, connected in a loop by four joints. Generally, the joints are configured so the links move in parallel planes, and the assembly is called a planar four-bar linkage.
