The correct answer is: C) The Constitution of India.
The Karnataka Constitution is the supreme law of the Indian state of Karnataka. It was adopted on 1 November 1956, and came into force on 1 November 1957. The Karnataka Constitution is primarily derived from the Constitution of India, which is the supreme law of India. The Karnataka Constitution also draws on the constitutions of other states in India, as well as on the constitutions of other countries.
The British Constitution is not a single document, but rather a collection of laws, conventions, and precedents that form the basis of the British government. The Constitution of the United States is the supreme law of the United States of America. It was adopted on 17 September 1787, and came into force on 4 March 1789. The Constitution of the United States is a written document that sets out the basic principles of the American government.
An original document is a document that is not a copy or a translation. The Karnataka Constitution is not an original document, as it is based on the Constitution of India.
