Explanation
Option A is correct because WS-BPEL (Web Services Business Process Execution Language) is specifically designed to orchestrate web services, and the processes it defines can be wrapped and exposed as SOAP-based web services themselves - meaning a BPEL process has a WSDL interface, accepts SOAP messages, and appears to external clients just like any other web service.
Option B is wrong because this is a core, well-documented capability of WS-BPEL: the specification explicitly supports the notion of an "abstract" and "executable" process, where executable processes are deployed to a BPEL engine that exposes them via SOAP endpoints.
Memory tip: Think of WS-BPEL as a "web service of web services" - it orchestrates multiple web services internally, but it also wears a web service costume on the outside (SOAP/WSDL), so callers can't tell the difference between a simple service and a full business process.
