Explanation:

Military regimes and dictatorships in Nigeria often suppressed dissent to maintain control. Restricting or banning government criticism was a common tactic to prevent unrest by silencing opposition and controlling public discourse. The other options are inconsistent with the authoritarian practices of these regimes, which typically limited political activity, resisted meaningful change, and did not target ethnic pride expressions as a primary unrest-prevention measure.

Answer:

prohibiting all criticism of the government.
