Whenever a website visitor views any page on your site, they trigger the page_view event. What if you wanted to define a new event to trigger when visitors land on a particular page (e.g., the homepage)? Once you've navigated to Events in the Google Analytics interface, which option would you choose to make this happen?

To define a new event based on existing events, like triggering an event specifically for homepage views, you would use the "Create event" option. This allows you to define custom events within the Google Analytics interface by setting conditions based on other events or parameters. "Modify event" is used to change an existing event's parameters or name, not to define a new event from scratch. "Mark event as conversion" designates an existing event as a key action for reporting, but doesn't create a new event. "Import event" is not a standard option for defining new events within the GA4 interface.
