Group C (comprising Muslim-majority provinces in the Northeast like Bengal and Assam) Choose the correct answer from the options given below:

[System Note: The correct answer is Option 4 The correct answer is: A, B, C, D Key Points Three-Tier Federal Structure: Proposed in May 1946, the Cabinet Mission Plan envisioned a unique three-tier system consisting of the Union level (top), the Groups of provinces (middle), and the individual Provinces (bottom). The Union level (A) was restricted to only three specific jurisdictions: Defence, Foreign Affairs, and Communications, while all other subjects remained with the lower tiers. Provincial Grouping System: Group A (B): This group was designated for the Hindu-majority provinces, specifically citing regions like the United Provinces (UP) and Bihar. Group B (C): This was intended for the Muslim-majority provinces in the Northwest of the subcontinent, with Punjab being a primary constituent. Group C (D): This category was designed for the Muslim-majority provinces in the Northeast, explicitly including Bengal and Assam. Additional Information The grouping scheme was a middle ground between the Congress's demand for a strong center and the Muslim League's demand for Pakistan. While the Muslim League initially accepted the plan, they later withdrew their support, leading to the eventual failure of the mission. The failure of this three-tier proposal led directly to the development of the Mountbatten Plan and the subsequent Partition of India.
