The correct option is User. The other roles that appear by default in a team managed project are Administrator, Member, and Viewer so they are not the correct choice.

Team managed projects use a simplified set of built in roles and the defaults are the Administrator, the Member, and the Viewer. There is no separate default User role in that project type, so User is the role that does not come preconfigured.

Viewer is an incorrect option because it is provided by default to grant read only access in team managed projects.

Administrator is an incorrect option because it is the built in role for project administration in team managed projects.

Member is an incorrect option because it is the default role used for normal project contributors in team managed projects.
