Answer:
The following are the ways a citizen can participate in the affairs of their country:
- 1) By voting in elections:
Every citizen of a democratic country has the right to vote in elections once they reach their legal voting age. This is one of the key ways a citizen can participate in the affairs of their country. By choosing a representative who they believe can strengthen the government, the citizen plays an important role as this person gets to be the next leader of the nation.
- 2) By joining political parties / political forces:
Once a citizen joins a political party, it means that he/she has understood the party ideology & finds it admirable and strengthening for the country.
- 3) By participating in party meetings:
By participating in party meetings, citizens can find out the new schemes organised by the government, the various rights they have, etc. They can also object to the policies if they have different opinions.
- 4) By becoming a representative:
Citizens not only have the right to vote but they can also stand as representatives whether individually or by joining a party. This way the cirltizen can directly interfere into the affairs of their country & express their views and opinions on the basis of public support.

NOTE:
*All these opinions are more likely to happen in democratic countries. In countries where monarchy, dictatorship or one party rule prevail, citizens might not get equal rights to participate in the affairs of their country.

A is the answer to your question
Answer:
Usually, the police tend to respect the rights of citizens and behave according to the rules of their profession, without overreaching and protecting citizens and their rights.
But on some occasions, police officers can overstep their roles and violate some constitutional rights of citizens, whether conscientiously or not.
In the latter case, the police often overstep their duties without the intention of doing so, but as a consequence of the situations to which they are exposed. Thus, for example, more than once a police officer has mistakenly shot a suspect who was in the middle of a persecution operation or at a crime scene, or even many times the police have arrested people who were not committing any crime, just for the simple fact of being suspicious.
