Answer:
c. Due process
Step-by-step explanation:
Due process is defined as the legal requirement of the government and the states to respect people's right and to treat them fairly based on the laws that have been established and not based on arbitrary decisions.
One of the guarantees that the 5th Amendment protects is this legal requirement, as it states: "No person shall (...) be deprived of life, liberty, or property, without due process of law." Therefore, if you were mistreated by a police officer during a routine traffic stop without just cause, that is to say, based on arbitrary reasons, the police violated the Due Process Clause, one of the fundamental guarantees of the U.S. Constitution.
