Which feature of YouTube channels helps to ensure students and parents have access to content?

The feature that effectively ensures students and parents have access to content is the automatic sharing of playlists on YouTube channels. When playlists are shared, it allows for a more organized way to present educational videos, making it easier for students and parents to find relevant content that aligns with specific learning objectives. This functionality promotes a more structured and accessible approach to learning resources, enabling both students and parents to engage with the material seamlessly.

The other choices do not enhance access to content in the same manner. While user accounts can facilitate personalized experiences, they do not inherently guarantee that students and parents will have access to the necessary content without additional steps. Limiting access to only certain videos could restrict the available material, which would not support broad accessibility. Lastly, promoting engagement through live chats enhances interaction but does not directly influence the accessibility of the educational content presented on the channel.
