Which three IP multicast address related statements are true？ （Choose three.） （）
A
Multicast addresses 224.0.0.0 through 224.0.0.255 are always forwarded because they are transmitted with Time to Live （TTL） greater than 1.
B
Multicast addresses 224.0.0.5 and 224.0.0.6 are source multicast addresses for OSPF routers.
C
Multicast addresses 224.0.0.13 and 224.0.0.22 are reserved link-local addresses used by PIMv2 and IGMPv3.
D
Because they would map to overlapping IP multicast MAC addresses， multicast addresses 224.0.1.1 and 238.1.1.1 could not be used together.
E
Multicast address 224.0.1.1 has been reserved for the Network Time Protocol （NTP） by the IANA
F
The administratively scoped multicast addresses 239.0.0.0 through 239.255.255.255 are similar in purpose to RFC 1918 private unicast addresses.
