The NEC does not permit the cord and plug connection to be used as the disconnecting means.
The answer to your question is b. Does not.
According to the National Electrical Code (NEC), a separate disconnecting means is required for appliances like ranges. This means that a cord and plug connection cannot be used as the only means to disconnect the range from the power supply. Instead, a separate disconnect switch or circuit breaker must be installed to safely disconnect the range.
For example, if there is an electrical issue with the range, the separate disconnect switch or circuit breaker can be turned off to completely cut off the power supply to the range. This ensures the safety of the person working on the range or performing maintenance tasks.
