Explanation:
B. Custom BeanPostProcessors can be implemented for Spring applications.
This is true because the BeanPostProcessor interface defines callback methods that you can implement to provide your own (or override the container’s default) instantiation logic, dependency resolution logic, and so forth1. You can configure multiple BeanPostProcessor instances, and you can control the order in which these BeanPostProcessor instances run by setting the order property1. For example, in this tutorial, a custom BeanPostProcessor is implemented to integrate Guava’s EventBus with Spring beans.
D. BeanPostProcessors are called during the initialization phase of a bean life cycle.
This is true because the BeanPostProcessor interface consists of exactly two callback methods: postProcessBeforeInitialization and postProcessAfterInitialization. When such a class is registered as a post-processor with the container, for each bean instance that is created by the container, the post-processor gets a callback from the container both before container initialization methods (such as InitializingBean.afterPropertiesSet() or any declared init method) are called, and after any bean initialization callbacks1.

Explanation:
Spring Security provides a fluent API for configuring web security based on URL patterns and request matchers. The authorizeRequests() method returns an expression that allows specifying access rules for different URLs using methods such as antMatchers(), regexMatchers(), mvcMatchers(), etc. The order of these rules matters, as they are evaluated from top to bottom. Therefore, it is recommended to put the most specific rules first and the least specific ones last.

Explanation:
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.
