A company has multiple users that need to modify the same document concurrently. Which of the following types of collaboration software would be BEST suited for this situation?

An email client is used for asynchronous communication and sending attachments, not for real-time concurrent editing of a single document.

Instant messaging is for real-time text-based communication between individuals or groups, not for modifying documents.

Web conference software facilitates real-time audio/video meetings and screen sharing, but it does not inherently provide tools for concurrent document editing.

Online workspaces or collaborative document platforms (e.g., Google Docs, Microsoft 365) are specifically designed to enable multiple users to view, edit, and comment on the same document in real-time. These platforms manage concurrent changes and version control to prevent conflicts.
