Explanation:

Maintaining a healthy back posture while standing requires proper spinal alignment. Keeping the spine aligned naturally helps distribute body weight evenly, reducing strain on muscles and ligaments. A head at a slight angle (a) can cause neck and back issues. Stiffening shoulders (b) leads to muscle tension. Raising on tiptoe occasionally (c) doesn't address core posture alignment. Natural spinal alignment (d) is fundamental for healthy standing posture.
