A grounded conductor is commonly referred to as a neutral conductor. This term specifically describes a conductor that is intentionally connected to the ground at one or more points in the electrical system. The primary function of the neutral conductor is to provide a return path for current and to facilitate the safe operation of electrical devices. By connecting the neutral to the ground, it helps ensure that in the event of a fault, the electrical system can effectively limit the voltage that might be accidentally present, thus enhancing safety.

The other terms present in the choices refer to different types of conductors in an electrical system. A hot conductor refers to a wire that carries live current, while a grounding wire serves to connect electrical devices or systems to the earth for safety purposes. A phase conductor, similar to a hot conductor, is involved in delivering current in an AC system. Thus, the neutral conductor is the only term that directly corresponds with the definition of a grounded conductor, making it the correct answer.
