Which of the following statements is true about epsilon?

Epsilon is a single cluster-wide quorum vote held by exactly one node at a time, not a per-replicated-database-unit construct.

Epsilon does not automatically relocate when the holding node reboots - the cluster must negotiate quorum without it, and epsilon must be manually reassigned after the node rejoins.

Epsilon can be manually moved from one node to another using the 'cluster modify -epsilon false' command on the current holder and 'cluster modify -epsilon true' on the target node. This is a supported administrative operation used during planned maintenance to control which node holds the tiebreaker vote in a cluster quorum.

This is factually incorrect because epsilon can be moved manually using cluster modify commands.
