D. An operation The REST Connect module in MuleSoft provides an operation for each method in the RAML (RESTful API Modeling Language) specification. An operation represents a specific action or function that can be performed on a resource, and it typically corresponds to an HTTP method (e.g., GET, POST, PUT, DELETE) defined in the RAML specification for a particular resource. So, for each method in the RAML specification, the REST Connect module in MuleSoft would provide an operation to handle the corresponding HTTP request.
