The correct answers are: 2) Hypertexts contain hyperlinks. 3) Hyperlinks are a kind of labyrinth.
Indeed, Hypertexts are texts that contain hyperlinks. Hyperlinks are nexus to data which is located elsewhere in the same text or in a completely different document. Hyperlinks can become very labyrinthine, used to create very complex mesh structures of web pages and nexuses to other websites.
The issue with definition 3 is that although it applies to certain types of hyperlinks it does not apply to links that actually direct the user to a different location within the same web page.
