Correct Option: A

A constitution in the formal sense, especially provisions by which change of the constitution is made more difficult than the change of ordinary laws, is possible only if there is a written constitution, if the constitution has the character of statutory law. Great Britain (United Kingdom) has no “written” constitution and hence no formal constitution, no solemn document called “the constitution.” Here the constitution has the character of customary law and therefore there exists no difference between constitutional and ordinary laws.
