A ZooKeeper client reads data from a Follower that is slightly lagging. How can the client ensure it receives the absolute latest state from the Leader?

1. A Invoke a `sync()` command before the read; this forces the Follower to synchronize its state with the Leader before returning data.
2. B Wait for at least 5 `tickTime` intervals to ensure the ZAB protocol has propagated all pending transaction logs.
3. C Perform a recursive checksum validation of the parent Znode to detect if the local replica is stale.
4. D Initialize a new TCP connection directly to the Leader's 2181 port and bypass the Follower entirely.
