A team uses SQL filters on a Service Bus topic subscription to route messages. Which SQL filter expression matches messages with property OrderType = 'Express'?

1. A OrderType = Express
2. B OrderType LIKE 'Express'
3. ✓ C OrderType = 'Express' (correct answer)
4. D WHERE OrderType = 'Express'

Shortcut: Service Bus SQL filters use SQL-like syntax with single-quoted string literals. OrderType = 'Express' matches messages where the user-defined property OrderType equals 'Express'.
