Refer to the exhibit. Which two conclusions can be drawn from the debug ip igmp output?()
A. The router sent an IGMP version 2 query out interface Ethernet1 at multicast address 224.0.0.1.B. Router RTA received an IGMP report version 1 from host 192.168.9.1.C. Reverse Path Forwarding (RPF) is ena bled for 192.168.9.4.D. Reverse Path Forwarding (RPF) is enabled for 224.0.1.40.E. The IP multicast groups are 224.0.0.1, 224.0.1.40, and 239.255.0.1.F. IP PIM RP mapping is static.
