Which of the following best explains how theocracy and absolute monarchy are similar?
a both were common governments for early river valley civilization
b both rely on a single individual as a source of power
c both require leaders to be voted into office once every four of six years
d both separate church and state

The correct option is B

Theocracy is the form of government where state administrators coincide with the leaders of the dominant religion, and government policies are identical or heavily influenced by the principles of the dominant religion. Absolute monarchy is a form of government in which the king has absolute power. In it there is no division of powers (executive, legislative and judicial). Although the administration of justice may have a relative autonomy in relation to the king, or there may be parliamentary institutions, the absolute monarch may change the decisions or rulings of the courts in the last resort or reform the laws at his will (The word of the king is law )
