Answer 1

Answer: (A)

1, 2, and 3

• Joints are points of contact between bones, or between bones and cartilages.
• Synovial joints are characterized by the presence of a fluid-filled synovial cavity between the articulating surfaces of the two bones. These joints help in locomotion and many other movements. Ball and socket joint is a type of synovial joint.
• Synovial joints are of following types: pivot, hinge, saddle, plane, condyloid, and ball-and-socket joints. Hence ball and socket joint, pivot joint, hinge joint are synovial joints.
• So, the correct answer is '1,2 and 3'.
