Answer:
B. Citizens think about political issues critically - Citizens make informed voting decisions
Step-by-step explanation:
A political system refers to all the institutions and interests groups that make or directly influence official government decisions, to how those institutions and groups function and interact with each other and how they interact with other systems (like the legal system and the economic system, for example).
In a democratic nation, one of the most efficient means that a citizen has to influence in a political system is the vote. Through the vote, citizens can elect their representatives so that they work according to certain social interests in order to improve society. Therefore, one main effect of informed citizens on the political system is the making of informed voting decisions, but this latter would not be possible if the voter did not think about political issues critically first.
