What developed when the number of newspapers increased after the Revolution?

Correct answer: Public discussion

The correct answer is public discussion. A larger number of newspapers meant that more reports, political arguments, and interpretations could reach readers. People could compare opinions, debate revolutionary events, criticise policies, and form views about rights and government. This growth of print culture helped create a public sphere in which political questions were discussed beyond the private world of rulers and nobles. It did not restore a secret monarchy, revive feudal privileges, or provide tax exemptions to nobles; those choices contradict the broad egalitarian and critical tendencies associated with revolutionary change. The important cause-and-effect relationship is simple: more newspapers produced wider circulation of information, which encouraged discussion and debate. Therefore option B is correct.
