Is it safe to use electrical appliances in the bathroom?

Using electrical appliances in the bathroom is generally not safe due to the high risk of electrical shock. Bathrooms are typically wet environments, which inherently increase the risk of electrical hazards. When water comes into contact with electrical components, it can create dangerous situations, such as short circuits or electrocution.

Safety regulations and standards often emphasize avoiding the use of electrical devices in bathrooms unless they are specifically designed for that purpose, such as certain types of hair dryers or shavers that have been tested and certified for safe use in wet environments. This is why the safest choice when considering the use of electrical appliances in a bathroom setting is to avoid using them altogether.

While supervision and waterproofing can potentially mitigate some risks, they do not eliminate the overall danger associated with using standard electrical appliances in this environment. Therefore, option B is the most appropriate answer.
