Which of the following are considered awkward positions that can lead to injury?

Reaching high, kneeling, and twisting are movements that can create awkward positions, significantly increasing the risk of injury. When a person reaches high, it often requires overstretching the shoulders and back, which can lead to strains or sprains. Kneeling can put pressure on the knees, and twisting the torso engages muscles in a way that may compromise stability and support, especially if done abruptly or while holding something heavy.

Each of these actions can disrupt the body's normal alignment and mechanics, leading to poor posture and physical stress. Unlike standing still, which may lead to fatigue over time, or maintaining good posture while sitting, which supports the spine, the actions described in the chosen answer involve a combination of movements that can place unnecessary strain on the body. Walking with a steady gait promotes stability and balance, further reducing the risk of injury. Therefore, it is the combination of reaching high, kneeling, and twisting that makes that choice the correct selection in terms of promoting injury risk.
