The correct answer is B. Neither of us uses any form of direct democracy.
Step-by-step explanation
Direct democracy is a type of democracy that is characterized by being exercised by citizens without the medication of any delegate, unlike representative democracy, which is one in which the government is exercised through representatives that arise from free elections that take place periodically. From the above, it can be inferred that one of the similarities between national and state governments is B. Neither of them uses any form of direct democracy because both use free elections to elect representatives of the people to govern.
