Which airport code is NOT associated with California?

The airport code B, SLC, is correct because it is the code for Salt Lake City International Airport, which is located in Utah, not California. The other codes mentioned are all associated with airports in California. SAN refers to San Diego International Airport, SFO is for San Francisco International Airport, and SJC is the code for San Jose International Airport. Each of these airports is situated within California, confirming that SLC is the only option not linked to this state.
