A Linux administrator is updating the group membership by executing the following commands: However, the group membership is not changing. Which of the following explains this issue?

The correct answer is C. The command groups was run with sudo privileges. Running groups with sudo shows the groups for the root user, not for the admin user. That’s why the output only shows root. Without sudo, groups admin (or re-login) would correctly show the updated group membership, including wheel.
