What semantic tag can hide the text inside of a details tag?

The semantic tag that can hide the text inside of a details tag is the summary tag. When using the details and summary elements in HTML, the summary tag acts as a visible heading for the content within the details tag. When the details tag is closed, the content is hidden from view, and the summary tag is shown as the clickable element that allows users to display the hidden content. This functionality enhances user experience by allowing for expandable and collapsible sections within web pages without the need for additional scripts, making it both user-friendly and accessible.

The other options don't serve this role: the hide tag is not an official HTML element, the content tag does not exist in the context presented, and the details tag itself is the container that holds both the summary and the hidden content, rather than a tag that hides text.
