The correct option is B.
A group is a feature that many social networks possess. The group feature allows users to create, post, comment and read the posts from a particular interest group to which they belong in the virtual community. The group may have open or close access and the group typically formed a smaller community within the larger one of that particular social network. Groups are usually managed by managers and moderators, who regulate members behavior and maintain decorum in the group.
