Which of following statements best describes an unwritten constitution?

An unwritten constitution is a type of constitution where the body of rules and laws cannot all be found in a single document. It refers to a constitution that has not been codified or written down in one comprehensive document, but instead derives from a combination of sources such as court judgments, conventions, and past practices. In an unwritten constitution, the source of the constitution is not from a single document, but rather from a collection of laws, precedents, and customs that have developed over time. This is different from a written constitution, where the body of rules and laws is contained in a single document.
