To answer this question, the user needs to have knowledge of UDDI registry and the types of information that can be found there.
UDDI (Universal Description, Discovery, and Integration) registry is a platform-independent, XML-based registry that provides businesses with a standard way to publish and discover information about web services. It is used to manage information about web services, such as their description, location, and interface.
Now let's go through each option:
A. White Pages: This is a type of information that can be found in the UDDI registry. It contains information about a business or organization, such as their name, address, phone number, and other contact details.
B. Yellow Pages: This is also a type of information that can be found in the UDDI registry. It contains information about a business's services or products, such as their description, category, and keywords.
C. Green Pages: This is a type of information that can be found in the UDDI registry. It contains information about a business's technical capabilities, such as the programming languages, platforms, and protocols they support.
D. Soap Messages: This is NOT a type of information that can be found in the UDDI registry. SOAP (Simple Object Access Protocol) messages are used to exchange information between web services, but they are not stored in the UDDI registry.
Therefore, the answer is: D. Soap Messages.
