Which CLI command do you use to shut down the 2.

The correct command to shut down the 2.4 GHz radio on a specific AP on a Cisco 3850 switch is ap name Floor1_AP1 dot11 24ghz shutdown. This command specifies the AP by name (Floor1_AP1), the radio frequency band (dot11 24ghz), and the action to be taken (shutdown). The other commands listed either reference the wrong frequency band, use incorrect syntax, or are not valid Cisco IOS commands for managing AP radios. References: CCNP Enterprise Wireless Design ENWLSD 300-425 and Implementation ENWLSI 300-430 Official Cert Guide
