The correct answer is B. Can better tell when public officials are not doing what they are supposed to do
Step-by-step explanation:
Being a knowledgeable citizen implies being well-informed or well-educated about politics, current events, government decisions and actions, conflicts in the nation, needs of citizens, etc. This has multiple benefits as it allows citizens to make informed decisions in elections, take actions to defend the rights of people and even monitor the government which means knowledgeable citizens can identify possible failures in the actions of public officials as they already know the actions and task of public officials and therefore can supervise them. Thus, one benefit of a knowledgeable citizen is that you "can better tell when public officials are not doing what they are supposed to do".
