The correct answer is B) it is not a guarantee that individual voices will be considered.
The statement that best describes a disadvantage of indirect democracy over direct democracy is that it is not a guarantee that individual voices will be considered.
In an indirect democracy, like in the United States, people vote to elect their representatives in Congress and for the President of the country. These representatives are the ones who make rules and have to listen to the people to know their demands and necessities in order to create better laws. But the disadvantage is that there is no guarantee that individual voices will be heard and then, considered. Representatives had to do what benefits the majority of people.
