Which of the following is an example of a right guaranteed by the concept of due process?

The concept of due process is rooted in principles that ensure fair treatment through the judicial system and that individuals have the opportunity to be heard before being deprived of life, liberty, or property. The right to make complaints without fear of punishment is a manifestation of due process as it affirms that individuals can express grievances and seek redress without facing retribution. This aligns with democratic principles where individuals are secured against unfair treatment and can advocate for their rights, making it a fundamental aspect of due process.

On the other hand, the other options do not align with the traditional interpretation of due process rights. Free public transportation is generally a public service issue rather than a due process right; collecting fees involves economic regulations and is not directly tied to individual protections under due process. Lastly, the right to remain anonymous in all situations is not a universally accepted right under due process, as there are occasions where identification is required for legal and administrative reasons.
