The correct answer is "Government leaders have limited powers."
The feature that is a characteristic of a democracy is "Government leaders have limited powers."
In a democracy such as the one in the United States, citizens have the right to participate in elections to vote and choose their President and representatives. It is the people who decide who their rulers will be. That is why the government has limited powers and representatives look for the interests of the citizens, not the interests of powerful groups that only look to fulfill their particular agendas.
