Correct Answer is (2).
Cartilage and cornea are devoid blood supply yest they require oxygen for respiratory need.
First option is incorerct because the knee joint is between three bones: the femur, tibia, and patella.
Third is incorrect as shoulder is ball and socket joint but elbow joints is hinge joint.
Fourth is incorrect as all premolars and molars do not have 3 roots.
