What happens when you archive a channel in Slack?

When you archive a channel in Slack, the channel becomes inactive and is no longer visible in the main channel list, which aligns with the correct answer. Archiving a channel is a way to preserve its content while making it unavailable for active discussions. Team members can still access the archived channel and its history, but they won't be able to send messages or make changes. This is particularly useful for keeping the workspace organized, as it allows teams to declutter their channel view without losing important information.

The other options do not accurately describe the archiving process. While a channel is not deleted permanently, it also doesn’t convert into a direct message group or restrict access to only admins. Instead, the purpose of archiving is to provide a way to manage channels that are no longer needed for active conversations without losing the valuable context and information that may still be referenced later.
