Which architectural style is described as stateless and uses standard operations for web services?

• A. GraphQL
• B. SOAP
• C. REST
• D. RPC

Answer: (C)

Statelessness and the use of standard HTTP operations describe RESTful web services. In REST, each request contains all the information needed to complete it, and the server does not rely on stored session context between requests. Interactions revolve around resources identified by URIs, with operations mapped to the standard HTTP methods like GET, POST, PUT, and DELETE, making the interface uniform and easily cacheable. GraphQL differs by using a flexible query language over a single endpoint rather than a set of standard HTTP actions; SOAP is a protocol with a fixed envelope and actions defined in WSDL; RPC emphasizes invoking procedures rather than manipulating resources. Because it embodies statelessness and standard HTTP operations, REST best matches the description.
