Which command lists hidden Yum groups?

• A. yum grouplist
• B. yum group list hidden
• C. yum grouplist hidden
• D. yum groups --hidden

Answer: (C)

Hidden groups in yum are those that aren’t shown by default in the group listings. To see them, use the grouplist subcommand with the hidden keyword. The best choice is to run yum grouplist hidden, which explicitly asks yum to display the groups marked as hidden in the repository metadata. This makes those otherwise-silent groups visible so you can inspect or install them if needed. Running yum grouplist without specifying hidden would typically show only the regular, non-hidden groups, and the other forms use different syntaxes that aren’t recognized for listing hidden groups in this context.
