Explanation

Option A is correct because for a GRE tunnel on the HQ router, the tunnel source should be HQ's own outgoing interface (GigabitEthernet0/0) and the tunnel destination must be the BR router's public IP address. Based on the exhibit, 209.165.202.134 is the BR router's public-facing IP address, making it the correct tunnel destination. The tunnel IP address 10.111.111.1 is a private overlay address used for the GRE tunnel itself, which is appropriate.
