This is true because the default scope of a bean in Spring is singleton, which means that only one instance of the bean will be created and shared by the entire application context. The @Bean annotation on the accountRepository() method indicates that this method will return a bean that will be managed by Spring. However, this method will not be called every time the bean is needed, but only once when the bean is first created. Therefore, only one AccountRepository bean will be instantiated and injected into the TransferService and AccountService beans.

B. A HelloService bean will be created from the helloService() method only when there is no other HelloService bean in the ApplicationContext.

This is true because the @ConditionalOnMissingBean annotation on the helloService() method indicates that this method will only be invoked to create a HelloService bean if there is no existing HelloService bean in the application context. This is a common way to provide a default bean that can be overridden by the user’s own bean definition.

D. This auto-configuration class is used only when the HelloService.class is on the classpath.

This is true because the @ConditionalOnClass annotation on the HelloAutoConfig class indicates that this class will only be loaded and processed by Spring Boot if the HelloService.class is present on the classpath. This is a common way to enable auto-configuration for a specific library or feature only when it is available.
