The show interfaces trunk command displays a list of interfaces currently operating as trunks, and their configuration (such as supported VLANs or frame tagging method). Sample output would resemble the following:
Switch# show interfaces trunk Port Mode Encapsulation Status Native vlan Gi0/1 desirable 802.1q trunking 1 Gi0/2 desirable 802.1q trunking 1 Port Vlans allowed on trunk Gi0/1 1-4094 Gi0/2 1-4094 <Output omitted>
This output indicates that switch ports Gi0/1 and Gi0/2 are both currently operating as trunks (Status), and that 802.1q frame tagging is being used on the trunk links.

The remaining options are incorrect because they are not valid Cisco IOS commands.
