The correct answer is: D. Sheikh Abdullah.
Sheikh Abdullah was the Prime Minister of Jammu and Kashmir from 1948 to 1953 and again from 1975 to 1982. He was a prominent leader of the National Conference party and a key figure in the state’s accession to India.
In 1951, Abdullah issued a proclamation regarding the establishment of a Constituent Assembly of Jammu and Kashmir. The Constituent Assembly was tasked with drafting a constitution for the state. The Assembly was elected in 1951 and completed its work in 1957. The Constitution of Jammu and Kashmir was adopted on 26 November 1957.

- Ghulam Mohammad Sadiq was the Prime Minister of Jammu and Kashmir from 1972 to 1975.
- Maulana Masoodi was a Kashmiri politician and religious leader. He was a member of the Constituent Assembly of Jammu and Kashmir.
- Yuvraj Karan Singh was the son of Maharaja Hari Singh, the last ruler of Jammu and Kashmir. He was the Regent of Jammu and Kashmir from 1952 to 1956.
