Which of the following countries has a series of documents and decisions that, taken collectively, are referred to as the Constitution but does not have one single document that can be called the Constitution?

The United Kingdom

The correct answer is Option 4- The United Kingdom

In most countries, ‘Constitution’ is a compact document that comprises a number of articles about the state, specifying how the state is to be constituted and what norms it should follow. When we ask for the constitution of a country we are usually referring to this document. But some countries, the United Kingdom for instance, do not have one single document that can be called the Constitution. Rather they have a series of documents and decisions that, taken collectively, are referred to as the constitution. So, we can say that constitution is the document or set of documents that seeks to perform the typical functions of a constitution.
