Final answer:
In Smartsheet, a Licensed User has the ability to create new items such as sheets, reports, and dashboards. Free Collaborators and Unlicensed Users have more limited capabilities, and cannot create new items.
Step-by-step explanation:
The type of user who has the ability to create new items in Smartsheet is a c. Licensed User. A Licensed User in Smartsheet has full access to create and edit sheets, reports, and dashboards within the platform. Free Collaborators can only view or edit sheets they've been shared to, depending on the permissions given, but cannot create new items. Unlicensed Users also have very limited capabilities and typically cannot create new items. System Administrators do have the ability to create new items, but this role is more about managing users and account settings, rather than day-to-day use of creating sheets. Therefore, the specific distinction of who can create new items points towards a Licensed User.
