Which of the following actions allows you to share an event with a collaborator?

The option that allows you to share an event with a collaborator is to create a public link.

By generating a public link, you can disseminate the necessary information effectively to all relevant stakeholders, facilitating collaboration and ensuring everyone has access to the latest updates regarding the event.
