The correct option is C Denial of rights to the minorities.
Denying voting rights to women is against democracy. For example, women in Saudi Arabia were not allowed to vote until 2015. In many countries, minorities are cornered and deprived of citizenship rights. The majoritarian government discriminates against the minorities. For example, the citizenship rules in Estonia are framed in a way that the Russian ethnic minorities find it difficult to get their right to vote. These instances are against political equality.
