Step 1: Recall the plain meaning of mandamus.
Mandamus literally means we command, and it directs someone to carry out a duty they are legally bound to perform.
Step 2: Eliminate the political and private options.
Directing the Prime Minister to dissolve the Cabinet or fixing minimum wages are political and policy matters, and directing a private company to pay salaries falls outside public duty, so none of these fit.
Step 3: Apply the correct scope of mandamus.
Mandamus is issued to a public official or authority to compel performance of a public duty they have failed to carry out.
\[ \boxed{\text{An official to perform public duty}} \]
