Explanation
Option D is correct because all three technologies play distinct but complementary roles in enabling data exchange between services. Choosing A, B, or C alone is incorrect - not because those options are false, but because they are incomplete; each one individually represents only part of the full answer.
- SOAP (Simple Object Access Protocol) is a messaging protocol that uses XML to structure and transmit data between services.
- HTTP is the underlying transport protocol that carries data across the web, used by both SOAP and REST-based services.
- WSDL (Web Services Description Language) describes a web service's interface - what operations it exposes and how to call them - enabling clients to know how to exchange data with it.
Memory tip: Think of it as sending a package - HTTP is the delivery truck, SOAP is the packaging format, and WSDL is the shipping manifest. All three work together to get data from one service to another.
