B. The multicast address 224.0.0.1 is a globally scoped address that has been reserved for the Network
Time Protocol (NTP) by the IANA.
C. Multicast addresses 239.0.0.0 through 239.255.255.255 are called limited scope addresses. They are
constrained to a local group or organization.

OSPF.

by a router.
