Which statement describes a reason why a group owner would configure a group to be viewable by group members only and require that new members be invited to the group?

The reason for configuring a group to be viewable by group members only and requiring new members to be invited is primarily rooted in the confidentiality of the group's content. When a group is set up with these restrictions, it ensures that sensitive information, particularly related to a specific project, is accessible only to those who have been vetted and are deemed trustworthy participants in that project.

This setup prevents unauthorized access, protects intellectual property, and maintains the integrity of the data being shared within the group. It encourages a controlled environment where only invited members can contribute to discussions or access documents, thus enhancing security and ensuring compliance with any necessary regulations related to data privacy and management.

The other options do not align with the need for such a restricted and controlled access setup. For instance, if the group needed to be open to all organizational members or if the content was already shared broadly, the owner wouldn't need to impose these limitations. Similarly, while controlling updates to existing content is important, it does not directly correlate with the confidentiality aspect that necessitates member invitations and restricted visibility.
