Solution
The correct answer is: To prevent the execution of default actions in response to an event trigger.
The event.preventDefault() command is used in JavaScript to prevent the browser from executing the default action that the event would trigger. For example, it can be used to stop a form from submitting or a link from being followed. This allows you to write custom behavior for these events instead.
