C Correct answer
Explanation

The JAX-WS Dispatch API allows dynamic service invocation without requiring compile-time WSDL or XML Schema. The Dispatch interface works directly with XML or SOAP messages, making it possible to invoke services when only the service endpoint and message structure are known at runtime. This is in contrast to static proxy generation which requires WSDL at development time.
