Final answer:
The article uses irony by describing Commonwealth authors as 'elitist' despite their dislike of the term 'Commonwealth literature.'
Step-by-step explanation:
The ironic aspect of the title of the article about Commonwealth authors' dislike of the term 'Commonwealth literature' is that the magazine depicts them as 'elitist,' which contradicts the authors' actual feelings towards the term.
This irony is evident in the fact that the authors are described negatively, despite their dislike of the term. It highlights the disconnect between how the magazine portrays the authors and their true opinions, adding irony to the title.
Therefore, the correct answer is option c) The magazine calls them 'elitist.'
