Correct Option: C

Constitutional monarchy is a form of government in which a monarch acts as head of state within the parameters of a constitution, whether it be a written, uncodified, or blended constitution. Most constitutional monarchies employ a parlia-mentary system in which the monarch may have strictly ceremonial duties or may have reserve powers, depending on the constitution. Under most modern constitutional monarchies there is also a prime minister who is the head of government and exercises effective political power. In Britain, the Glorious Revolution of 1688 led to a constitutional monarchy restricted by laws such as the Bill of Rights 1689 and the Act of Settlement 1701, although limits on the power of the monarch are older than that.
