What aspect of electronic documents does hypertext enhance?

Hypertext enhances the ability to link different pieces of information within electronic documents. This feature allows users to navigate seamlessly from one section of a document to another or between different documents entirely, providing a non-linear approach to information retrieval.

For example, when you click on a hyperlink, it directs you to relevant text, external websites, or additional resources that expand on the topic. This interconnectivity makes it easier to explore related information without having to search for it manually or remember where it is located.

The other options do not capture the primary function of hypertext. While readability, formatting, and security are important elements of electronic documents, they do not directly relate to the concept of hypertext, which focuses on the relationships and connections between different information artifacts.
