Which statement about the MPLS LDP router ID selection is correct?

The correct statement is that the loopback with the highest IP address is selected as the LDP router ID. LDP prioritizes loopback interfaces because they are always up, providing a stable identifier. If multiple loopbacks exist, the one with the highest IP address is chosen. If no loopback is configured, LDP selects the highest IP address of an active physical interface. The LDP router ID does not necessarily have to match the IGP router ID, though it's often configured to for consistency. The force keyword in LDP router ID configuration causes a restart of the LDP process, impacting established LDP sessions.
