You need to implement a Distributed Queue where multiple producers push tasks. How does the 'Sequential' Znode flag provide the necessary ordering primitive?

1. A It forces the leader node to buffer incoming requests until a majority of followers reach a consistent timestamp.
2. B It automatically appends a monotonically increasing counter to the Znode name (e.g., `task-0000000001`), ensuring a total global order within the parent path.
3. C It sorts the underlying transaction log by the client's session ID to prevent out-of-order execution.
4. D It prevents duplicate writes by hashing the data payload and mapping it to a unique integer ID.
