If a workstation is configured with an address of 224.0.0.1, which functionality will it allow?
The correct answer is C. multicasting to the local subnet. The address 224.0.0.1 falls within the Class D multicast range and specifically represents the 'All Hosts' multicast group for the local subnet.

Why each option
The address 224.0.0.1 falls within the Class D multicast range and specifically represents the 'All Hosts' multicast group for the local subnet.
Loopback addressing uses the reserved range 127.0.0.0/8 - specifically 127.0.0.1 - to redirect traffic back to the same host without traversing a network interface.
Subnet broadcasting uses either the limited broadcast address 255.255.255.255 or the directed broadcast address formed by setting all host bits to 1, not an address in the 224.x.x.x range.
Addresses in the range 224.0.0.0 through 239.255.255.255 are reserved for IP multicast, where traffic is delivered to a group of interested receivers rather than a single host or all hosts.
Automatic Private IP Addressing (APIPA) uses the 169.254.0.0/16 range, assigned automatically by a host when a DHCP server is unreachable.
