When a neutral wire is disconnected in a circuit, it can create a shock hazard and lead to improper operation of appliances. This is because the neutral wire serves as a return path for current in an electrical circuit. Without this connection, the voltage in the circuit can become unbalanced.

For instance, with no neutral, some appliances may become energized through alternative paths created by the circuit, potentially causing parts of the appliance to carry voltage without proper grounding. This indeed increases the risk of electric shock to anyone handling the appliance, as they may complete a circuit unintentionally. Furthermore, appliances designed for a balanced input voltage may malfunction or operate erratically due to the uneven distribution of voltage, leading to ineffective performance or damage.

The other options pose scenarios that do not accurately reflect the consequences of a disconnected neutral. Therefore, the acknowledgment of the risks associated with a disconnected neutral further emphasizes the critical role it plays in maintaining safety and functionality within electrical circuits.
