A person climbing a hill leans forward to increase stability. Leaning forward shifts the center of mass towards the hillside, improving balance and reducing the risk of falling backward. This position also allows for better utilization of leg muscles and reduces the strain on the back.

A person climbing a hill leans forward to increase stability (D). Leaning forward shifts the center of mass towards the hillside, enhancing balance and reducing the risk of falling backward. This posture allows the individual to maintain a more stable foothold, minimizing the chance of slipping. Additionally, leaning forward enables better utilization of leg muscles, providing more power for propulsion uphill. It also reduces the strain on the back by distributing the load more evenly across the body. While leaning forward may contribute to a perception of increased speed, its primary purpose is to enhance stability and safety during the ascent. Therefore, the correct option is (D) to increase stability, as it aligns with the biomechanical advantages and safety considerations associated with leaning forward while climbing a hill.
