To solve this question, the user needs to have basic knowledge of web services and their components.
Web services are a standardized way of exchanging data between different systems over the internet. They are made up of multiple components, each serving a different purpose.
The correct option is:
B. XML and HTTP
Explanation:
Web services typically use the XML (Extensible Markup Language) protocol to format the data being exchanged between systems, and the HTTP (Hypertext Transfer Protocol) protocol to transmit the data over the internet.
Option A is incorrect because SOAP (Simple Object Access Protocol) is a messaging protocol used to exchange structured data between applications. It is often used in conjunction with XML in web services.
Option C is incorrect because WSDL (Web Services Description Language) is an XML-based language used to describe the functionality offered by a web service, while UDDI (Universal Description, Discovery, and Integration) is a platform-independent, XML-based registry for businesses to list their web services.
Option D is incorrect because eb-XML (Electronic Business using eXtensible Markup Language) is a set of modular specifications for conducting business over the internet using XML, while WSDL is a language used to describe web services.
Therefore, the correct answer is:
The Answer is: B. XML and HTTP
