When a change is detected in Angular, the framework's response involves updating the template bindings to reflect changes in the model. This process is crucial as Angular follows a data binding methodology where the model and the view are in sync. When an event occurs, such as user input or a data fetch, Angular's change detection mechanism kicks in. It checks for any updates in the models, and if changes are found, it will automatically update the corresponding bindings in the templates. This ensures that the user interface accurately represents the current state of the application, providing a seamless and interactive experience.

The other options do not accurately describe Angular's behavior upon change detection. For instance, while Angular does utilize a change detection strategy, it doesn’t activate all change detectors immediately—this would be inefficient. Additionally, Angular does not reboot the entire application upon detecting changes, as that would disrupt the user experience and be unnecessary. Finally, logging changes for future reference is not part of the change detection process; Angular's goal is to immediately reflect changes in the view rather than just keeping a record of them.
