🧠 Explanation:
- The All-India Muslim League joined the interim government of British India on 26 October 1946.
- This decision came after initial hesitation, following negotiations with the British and the Indian National Congress.
- The interim government was formed under the Cabinet Mission Plan to prepare for India’s full independence.
- Therefore, 1946 is the correct year when the Muslim League officially became part of the interim administration.
