An application uses a Service Bus topic with three subscriptions. Message A is sent with no filters. How many copies of the message do consumers receive in total?

1. A 1 (only first matching subscription)
2. ✓ B 3 (one per subscription) (correct answer)
3. C 0 (needs explicit routing)
4. D Depends on delivery count

Shortcut: Each active subscription with a matching filter (default filter is True, matches all) receives one copy of the message. Three subscriptions = three independent message copies.
