Correct answer: (D) Semantic web

Explanation

The Semantic Web is the Web 3.0 component that describes things so computers can understand them.

It adds machine-readable meaning to data through structured metadata.

Social tagging lets users label content but does not give machine meaning.

A sustaining web is not the component that encodes machine understanding.

The social web centres on human interaction rather than machine comprehension.

Linked data and ontologies are core building blocks of the Semantic Web.
