Correct answer: Continuity for each member link of a link aggregation group must be verified., Each member link of a link aggregation group must run BFD..
Why this is the answer
Micro-BFD is designed to monitor the individual member links within a Link Aggregation Group (LAG) or EtherChannel. Therefore, "Each member link of a link aggregation group must run BFD" and "Continuity for each member link of a link aggregation group must be verified" accurately describe its behavior. This ensures that if a single link fails, BFD quickly detects it, allowing the LAG to remove the failed link and maintain connectivity with the remaining active links. The other options are incorrect because BFD can run on any link, not just high-bandwidth ones, and the 3x3 ms timer is a configuration detail, not a goal of micro-BFD itself.
