Explanation
B is correct because in stream processing frameworks like Apache Storm, a topology runs indefinitely by default - it must be explicitly killed or stopped by the operator. Topologies are designed to continuously process streaming data, so there is no built-in notion of "task completion" that would trigger an automatic shutdown.
Why A is wrong: Assuming a topology self-terminates leads to resource mismanagement in production; workers and slots remain occupied until the topology is manually decommissioned, which is exactly why operators must issue an explicit kill command.
Memory tip: Think of a topology like a factory assembly line - it keeps running 24/7 until someone hits the shutdown switch. "Topology = perpetual pipeline, not a one-shot script."
