The correct answer specifies that track lighting should not be installed within 3 feet horizontally and 8 feet vertically from the top of a bathtub rim. This guideline is based on safety regulations and standards intended to prevent the risk of electrical shock in areas where water is present.

The horizontal distance of 3 feet helps ensure that electrical fixtures are far enough away from splashes or potential water contact, minimizing hazards associated with damp environments. The vertical distance of 8 feet creates a safe zone that prevents any electrical hazard from being in close proximity to water sources that could lead to dangerous situations.

In the context of electrical installations, especially in wet or damp locations such as bathrooms, adhering to these distances is crucial for ensuring compliance with the National Electrical Code (NEC) and maintaining a safe environment for users. Using appropriate measurements helps electrical professionals and homeowners prevent accidents that could occur if water were to come into contact with electrical fixtures.
