Based on the following passage, which of the following assumptions is most likely true?
The National Electrical Code (NEC), first published in 1897, is the authoritative guide to all matters regarding safe electrical installation, design, and inspection; it is updated and published every three years by the National Fire Protection Association. It is not a federal law, but most states have adopted the code, making it standardized across the United States.
The NEC contains mostly obsolete information about electrical systems from the early 20th century.
The federal government writes the NEC but does not enforce it.
Because it is used in so many states, the NEC varies according to location.
One purpose of the NEC is to prevent electrical fires.
