What is the significance of the concept of 'one person, one vote'?

The concept of 'one person, one vote' holds significant importance in democratic systems as it guarantees equal representation in electoral districts. This principle ensures that each individual's vote carries the same weight, fundamentally supporting the idea that everyone should have an equal say in the political process. By promoting equal representation, it aims to prevent the dilution of votes and ensures that electoral districts are drawn in a manner that fairly reflects the population, thus upholding the democratic ideals of fairness and equality.

While the other choices touch upon aspects of democracy, they do not capture the core essence of this principle as effectively. Emphasizing majority opinions can lead to the marginalization of minority viewpoints, making it an incomplete reflection of civic equality. Making all votes count equally specifically emphasizes the weight of the votes rather than the structural equality in representation, and the idea of reinforcing the authority of the federal government does not align with the fundamental goal of ensuring each citizen's voice is equally valued in a participatory democracy. Therefore, the chosen answer highlights the crucial aspect of equal representation integral to upholding the democratic process.
