What step must the administrator take to resolve this issue?

An administrator has created a VPN community within VPN Manager on FortiManager. They also added gateways to the VPN community and are now trying to create firewall policies to permit traffic over the tunnel; however, the VPN interfaces are not listed as available options.

What step must the administrator take to resolve this issue?
A . Install the VPN community and gateway configuration to the FortiGate devices, in order for the interfaces to be displayed within Policy & Objects on FortiManager
B . Set up all of the phase 1 settings in the VPN community that they neglected to set up initially. The interfaces will be automatically generated after the administrator configures all of the required settings.
