Category approval

Approval of content can also be configured for specific categories. This can be useful if certain categories tend to attract heated/difficult discussions, unusual amounts of human spamming, or otherwise need extra moderation attention. Site owners can configure all new topics and/or all new replies to require moderator approval before being posted.

You can see more details on it here Category Group Review/Moderation
