What is a potential injury from electric shock?

C is the most appropriate choice as a potential injury from electric shock because electric currents can severely affect the nervous system. When an individual experiences an electric shock, the current can disrupt normal nerve function, potentially leading to nerve injuries. Such injuries may manifest as loss of muscle control, which can impair voluntary movements and overall coordination. The severity of these effects depends on the intensity of the current, the path it takes through the body, and the duration of exposure.

While hearing loss, vision impairment, and skin rashes can occur due to other conditions or exposures, they are not primary potential injuries specifically linked to electric shock in the same way that nerve injury and loss of muscle control are. Electric shock primarily impacts the nervous system, making the chosen answer the most relevant in this context.
