Answer 1

Correct answer is (c) the chondrocytes in articular cartilage become lesser in number

Easiest explanation: Articular cartilage is the cartilage at the lining of the extremities of the long bones. It helps reduce friction and has chondrocytes. It has no blood supply and takes and nourishment from the synovial fluid. Drying of the synovial fluid and loss of chondrocytes causes pain in the joints.
