Do not answer if you do not know:

in which type of government do citizens elect the country's leader?

a) republic
b) monarchy
c) dictatorship
d) parliament

Leaders are elected in a republic. Monarchies are when the king/queen rules, the title is usually hereditary and not elected. A dictatorship is kind of the exact opposite of a republic (and they usually force themselves to power militarily). Parliament basically is a system set in place to watch the government and make sure they're not doing anything bad (at least that's what I learn from Google).

Replubic;a state in which supreme power is held by the people and their elected representatives, and which has an elected or nominated president rather than a monarch.

BTW thing like just look the definition up people say oh she or he is so smart they use big words all the time but just definition searching
