B Correct answer
Explanation

WSDL (Web Services Description Language) is an XML-based specification that describes how to access a web service. It defines the service endpoint, operations, message formats, and protocols. UDDI is for discovery/registry, SOAP is for messaging, and ESB is an integration architecture pattern - none of these describe the access interface itself.
