Option (C) is incorrect because the Preamble does not have the same legal effect as enforceable parts like Fundamental Rights. 6. Option (D) is the most accurate description. The Preamble is a part of the Constitution and serves as a key to understanding the minds of the constitution-makers and interpreting the provisions of the Constitution. Its legal effect arises only in conjunction with other parts of the Constitution, not independently.
