Answer
Annotations are available at runtime. Frame the concept in practical terms so you can explain it during interview discussion.
RetentionPolicy.RUNTIME indicates that annotations are accessible during runtime via reflection, allowing frameworks to use annotations for configuration and behavior modification dynamically. For example, in a testing framework, annotations like @Test can be detected and executed at runtime.
