The correct response is: The people of Kashmir had voted to be part of India.
In 1947, when British India was partitioned into India and Pakistan, the princely states had the option to join either country. Maharaja Hari Singh, the ruler of Kashmir, initially wanted to remain independent. However, after an invasion by tribal forces from Pakistan, he sought military assistance from India, which led to the accession of Kashmir to India under certain conditions. The conditions included a promise of a plebiscite to determine the will of the people regarding their future.
