Answer: B

Explanation:

The @Component annotation indicates that a class is a candidate for auto-detection by Spring and can be registered as a bean in the application context. However, to enable this feature, the Java configuration class must also have the @ComponentScan annotation, which tells Spring where to look for annotated components.
