• C. P - Pivot joint

• D. P - Hinge joint

Answer 1

The correct option is B

P - Hinge joint
Q - Ball and socket joint

In the chart, 'P' is hinge joint and Q is ball and socket joint. Hinge joints are like door hinges which allows only back and forth movement. E.g: Fingers and toes, knee, elbow, etc. In ball and socket joints, one bone is hooked into hollow space of another bone. This type of joint helps in rotatory movement. E.g: Shoulder.
