The correct answer is D. A democracy is governed by citizens who participate equally; a theocracy is governed by religious leaders and laws.
Step-by-step explanation:
Democracy and theocracy are both political systems but they differ greatly on their features. In the case of democracy, the government is chosen by all the population usually through votes that determine those who will represent the population and take important decisions, this means it is the citizens the ones that choose the government by participating equally and this government should represent all the citizens. On the other hand, in a theocracy the government is composed by religious leaders and members who are not elected by citizens but by the church itself, also, these religious leaders govern according to religious laws or the laws of God and act in name of god and not in name of the citizens.
Considering this, the statement that best explains the difference between a democracy and a theocracy is "a democracy is governed by citizens who participate equally; a theocracy is governed by religious leaders and laws" because in a democracy the citizens choose the government and can participate in equal terms by voting, while in theocracy the ones that govern are the religious leaders who follow the laws of God instead of the opinion of the citizens.
