Explanation:
Oracle STS leverages the WS-Trust standard protocol to manage token exchange
between the Web Service Client (WSC) and the Web Service Provider (WSP) (not C). WS-Trust
provides a standard way to send security token requests to any Security Token Service (STS) (not
D). This specification can be used to manage token transformation when crossing the various
security boundaries of the information system (not B).
