Why each option
Cisco WGB and public safety features are supported on 2.4 GHz, 5 GHz, and the 4.9 GHz public safety band. The 4.9 GHz band is a dedicated spectrum for first-responder and public safety deployments.
5 GHz alone omits the 2.4 GHz and 4.9 GHz bands that are also supported for WGB and public safety operation.
2.4 GHz alone omits both the 5 GHz standard band and the 4.9 GHz public safety band supported by Cisco WGB.
Cisco APs supporting WGB operation allow association on both standard Wi-Fi bands (2.4 GHz and 5 GHz) as well as the 4.9 GHz band, which is a licensed spectrum allocated specifically for public safety communications in the US. This makes option C the only answer that accounts for all supported radio bands including the public safety-specific frequency.
Limiting to 2.4 or 5 GHz omits the 4.9 GHz public safety band, which is a key part of Cisco's public safety wireless support.
