Final answer:
A system of government where laws are based on official religious beliefs and constitutional law is known as a theocracy, rather than any of the options provided.
Step-by-step explanation:
Theocracies are led by religious authorities and implement laws derived from religious texts or divine guidance.
The system of government in which constitutional law is combined with the recognition of an official state religion and some use of religious beliefs or texts as a foundation for law is known as a theocracy. A theocracy typically has a religious hierarchy at its helm, governing the state according to divine guidance or under the belief that officials are divinely inspired. This differs from a purely secular government, where laws are created through democratic consensus and are not specifically based on religious texts or edicts. However, the term theocracy is distinct from the options provided, as none of them accurately describe the system of government in question.
Within a theocracy, religious officials may administer laws or policies based on religious doctrine, which are often reflected in the state's constitution. Examples of theocracies include Iran, where the political and religious leadership are interwoven, and historical examples like the pantheons of Egypt and Greece. Contemporary theocracies may enact theonomic laws, and contrary to other forms of governments that might endorse a state religion or be influenced by religious morals, a theocracy is explicitly ruled by religious authorities.
