Options

Explanation

Option C is correct because UDDI (Universal Description, Discovery, and Integration) is the industry-standard protocol specifically designed for publishing and discovering web services through a searchable registry - it acts like a "yellow pages" for services on a network.

Option A is wrong because WS-Addressing is a specification for routing and referencing messages and endpoints (essentially providing a standard way to "address" a message to a service), not a mechanism for searching or discovering services.

Option B is wrong because WS-BPEL (Business Process Execution Language) is used to orchestrate a sequence of web service calls into a business workflow - it assumes you already know which services to use, and has nothing to do with finding them.

Memory tip: Think of UDDI = "U Discover, Deploy, Integrate" - the double-D in UDDI stands for Description and Discovery, which are its two core functions. If an exam question mentions finding or searching for a service, UDDI is almost always the answer.
