Which collaborative feature does Google Jamboard offer?

Google Jamboard is designed specifically for collaboration, allowing users to work together in real-time on a digital whiteboard. This feature enables multiple users to contribute simultaneously, making it easy to brainstorm, share ideas, and provide feedback instantly. Collaboration is enhanced by visual elements, such as drawing or adding sticky notes, which can be seen and edited by all participants as changes occur.

The other choices, while useful features in various contexts, do not encapsulate the primary focus of Google Jamboard. Document storage, for instance, is more relevant to Google Drive, where files can be saved and managed rather than actively collaborating in real-time on a visual platform. Video playback is not a core function of Jamboard, as it is primarily a tool for interactive engagement rather than media playback. Text-to-speech functionality is not inherently built into Jamboard's collaborative features, as its focus is on creating a shared space for visual collaboration instead of providing accessibility features for auditory engagement.
