Which of the following is a decision of the Supreme Court of India on promissory estoppel?

In "Delhi Cloth and General Mills Ltd. v. Union of India" (1987) the Supreme Court examined the doctrine of promissory estoppel against the Government and the requirement that the promisee should have altered his position on the faith of the promise. Kedar Nath v. Gorie Mohamed (1886) was decided by the Calcutta High Court and is a case on consideration for a subscription promise under section 2(d) of the Indian Contract Act, 1872, so it is not a Supreme Court decision and the choice naming both cases is wrong.
