To configure an OData service for a transactional SAPUI5 application, you need to use the SAP Cloud Application Programming Model (CAP) and the SAP Fiori Elements framework. The CAP provides a declarative and consistent way to define and expose data models and services as OData v4 endpoints. The SAP Fiori Elements framework provides generic UI templates and controllers that can consume OData v4 services and support CRUD (Create, Read, Update, Delete) operations. The default data access behavior of the OData service is to allow all CRUD operations, unless you specify otherwise in the service definition or the annotations.
The other options are not correct because:
* B. Read: Yes Create: Yes Update: Yes Delete: No: This is not the default data access behavior of the OData service, but it can be achieved by setting the @Deletable annotation to false for the entity or the entity set in the service definition or the annotations.
* C. Read: Yes, Create: No Update: Yes Delete: No: This is not the default data access behavior of the OData service, but it can be achieved by setting the @Creatable annotation to false for the entity or the entity set in the service definition or the annotations.
* D. Read: Yes, Create: No Update: No Delete: No: This is not the default data access behavior of the OData service, but it can be achieved by setting the @Creatable and @Updatable annotations to false for the entity or the entity set in the service definition or the annotations.
