The correct option is Muslims, Sikhs, General.
Explanation
The Cabinet Mission Plan (1946) formulated the scheme for the composition of the Constituent Assembly of India. It established specific criteria for the distribution of seats among the British Indian Provinces.
- Basis of Allocation: The seats allocated to each province were determined roughly in proportion to their respective populations, typically in the ratio of one seat per million people.
- Community Classification: The seats within each province were distributed among the three main communities recognized by the Plan in proportion to their population. These three communities were:
- Muslims
- Sikhs
- General (all communities other than Muslims and Sikhs).
The "General" category encompassed Hindus, Christians, Parsis, Anglo-Indians, and Scheduled Castes/Tribes, who were not provided separate electorates or distinct categorization for the purpose of the Constituent Assembly elections under this specific plan.
Key Takeaway: The Cabinet Mission Plan divided the provincial electorate into exactly three categories for seat allocation: General, Muslims, and Sikhs.
