Final answer:
Distraction injuries of the spine are most commonly the result of diving into unfamiliar ponds or waters. This can be attributed to misjudging the depth, impact with the bottom, and encountering unseen obstacles in the water. The correct option is d).
Step-by-step explanation:
Distraction injuries of the spine are MOST commonly the result of diving. When people dive into unfamiliar ponds or waters, they may sustain neck and spinal injuries due to various factors:
Shallow water: When an object is submerged in water, it appears to be at a shallower depth than it actually is. This can lead to misjudgment and diving into water that is too shallow, causing spinal injuries.
Impact with the bottom: Divers may not be aware of the depth of the water and can hit the bottom with significant force, resulting in neck and spinal injuries.
Unseen obstacles: Ponds or waters may contain hidden obstacles such as rocks or debris, which can cause severe injuries if a diver comes into contact with them. Option d) is the correct one.
