Which of the following is a feature of Google Sheets that promotes collaboration?

Simultaneous editing and chat features are fundamental to promoting collaboration in Google Sheets. This functionality allows multiple users to work on the same document at the same time, facilitating real-time updates and contributions. As users make changes, those modifications are immediately visible to all collaborators, thus enhancing productivity and reducing the potential for version control issues.

Moreover, the integrated chat feature allows users to communicate directly within the document environment without needing to switch to another application. This seamless interaction fosters teamwork by enabling users to discuss changes, provide feedback, or ask questions right where the work is happening. Combining simultaneous editing with chat makes the collaboration process more efficient and effective, encouraging users to engage constructively on shared projects.

In contrast, other options do not specifically enhance collaborative efforts as directly. Single-user editing mode restricts input to one person at a time, which does not promote teamwork. Generating automatic reports, while useful, does not involve real-time collaboration amongst users. File export options, although beneficial for sharing documents outside of Google Sheets, do not facilitate ongoing collaborative efforts within the platform.
