With reference to the legal status and amendability of the Preamble of the Indian Constitution, which of the following statements is correct?

Explanation

In the landmark Kesavananda Bharati case (1973), the Supreme Court held that the Preamble is an integral part of the Constitution. It can be amended under Article 368, but such amendments cannot alter or destroy its 'basic structure'. It is non-justiciable and not directly enforceable in courts.
