With reference to the structural provisions and the grouping scheme proposed under the Cabinet Mission Plan of May 1946 , consider the following statements: I. The plan proposed a three-tier federal structure where the Union level was restricted to jurisdiction over defence, foreign affairs, and communications. II. Group B was designed to include the Muslim-majority provinces of the northeastern region, specifically including Assam. III. Group A was designated for the Hindu-majority provinces within the proposed federal arrangement. IV. The plan envisioned a middle tier of 'Groups' situated between the central Union and the individual Provinces. Choose the most appropriate answer from the options given below:

The Correct answer is: I, III and IV Only Important Points Statement I is correct: The Cabinet Mission Plan of May 1946 proposed a three-tier federal structure. At the top was the Union, which was given authority only over specific subjects: defence, foreign affairs, and communications. Statement II is incorrect: According to the plan's grouping scheme, Group B was reserved for the Muslim-majority provinces in the northwestern part of India. It was Group C that was designated for the Muslim-majority provinces in the northeast , including Assam. Statement III is correct: The plan categorized the provinces into three groups based on their majority population. Group A specifically consisted of the Hindu-majority provinces. Statement IV is correct: The proposed federal structure was characterized as 'three-tier' because it established the Union at the top, the individual Provinces at the bottom, and an intermediate tier known as 'Groups' (Groups A, B, and C) to which provinces would belong. Additional Information The failure of the Cabinet Mission Plan to reconcile the differences between the Indian National Congress and the Muslim League led directly to the formulation of the Mountbatten Plan (3 June Plan). While the Muslim League initially accepted the plan before withdrawing, the Congress accepted the grouping scheme but with significant reservations. The collapse of these negotiations served as the immediate precursor to the Partition of British India into the dominions of India and Pakistan.
