The correct option is Individual Email Address.

Individual Email Address cannot be added to team-managed project notification settings because team-managed projects only let you choose recipients that are defined inside the product such as users, roles, and groups. Team-managed notification configuration does not accept arbitrary external or freeform email addresses as recipients.

Signed In User is incorrect because team-managed projects allow you to notify users who are signed into the site and who are part of the project.

Project Role is incorrect because roles defined in the project can be selected as notification recipients in team-managed projects.

Project Manager is incorrect because the project manager or project lead role can be used as a recipient in the project notification settings.
