B . The classes are eligible for handling requests in Spring MVC.
This is true because the @Controller annotation marks a class as a web request handler, and it is typically used with the @RequestMapping annotation to map specific URLs to methods1. The @Controller annotation also allows the class to be recognized as a Spring-managed component through the classpath scanning2.
E . The @Controller annotation is a stereotype annotation like @Component.
This is true because the @Controller annotation is a specialization of the generic stereotype @Component annotation, which allows a class to be recognized as a Spring-managed component3. The @Controller annotation extends the use-case of @Component and marks the annotated class as a business or presentation layer4.

Spring Boot provides a set of tools for improving the development experience, such as automatic restart, live reload, remote debugging, etc. These tools are included in the spring-boot-starter-devtools dependency, which can be added to the project's pom.xml or build.gradle file. The automatic restart feature will monitor the classpath for changes and trigger a restart of the application when necessary.
