A system which provides support with a variety of joints that enable a wide range of movements is:

Correct option is B

Ans. (b)
Sol. The skeleton is the body's framework that provides support, protection, and movement. It consists of 206 bones in an adult human and is connected by joints, which allow a wide range of movements. The skeletal system works alongside the muscular system to facilitate motion.
Explanation of each option:
· (a) The spine and discs – Incorrect. The spine provides support and flexibility but does not account for all types of joint movement in the body.
· (b) The skeleton – Correct. The skeletal system provides structural support and movement through various types of joints (e.g., ball-and-socket, hinge, pivot).
· (c) The peripheral nervous system – Incorrect. The peripheral nervous system (PNS) transmits signals between the brain, spinal cord, and body but does not provide structural support.
· (d) The central nervous system – Incorrect. The CNS (brain and spinal cord) controls body functions and movement but does not provide mechanical support or movement through joints.
Thus, the correct answer is (b) The skeleton, as it supports the body and enables movement through various joints.
