The correct option is C pivot joint
A joint is a junction where two or more bones meet. They aid in movement.
Joints are of various types:
∙ The joint that connect our neck to head is called a pivot joint. It allows movement of neck in the forward and backward direction, as well as sideways movement.
∙ Hinge joint allows back and forth movement. It is found in ankles, elbows and knee joints.
∙ Ball and socket joints form when a bone ending with a ball like structure fits into the socket of adjacent bone. The bone with a ball can move nearly in all directions. These joints are present in hip and shoulder.
∙ Fixed joints don't permit any movement and are extremely strong. They are present between various bones of the skull.
