Correct Option
The members of the Constituent Assembly from the Provinces were elected by the Provincial Legislative Assemblies. The Constituent Assembly was constituted under the Cabinet Mission Plan of 1946. Members from the British Indian Provinces were indirectly elected by the members of the Provincial Legislative Assemblies. These provincial assembly members themselves were elected on a limited franchise. The total strength of the Constituent Assembly was 389, comprising 292 members from British Indian Provinces, 93 from Princely States, and 4 from Chief Commissioner's Provinces. Members from Princely States were nominated by their respective rulers.
