According to the Cabinet Mission plan, how many seats were allotted to the Princely States in the Constituent Assembly?

93

The correct answer is Option 4- 93

The Princely States were allotted a minimum of 93 seats in the Constituent Assembly.

Formally, the Indian Constitution was made by the Constituent Assembly which had been elected for undivided India. It held its first sitting on 9 December1946 and reassembled as Constituent Assembly for divided India on 14 August 1947. Its members were chosen by indirect election by the members of the Provincial Legislative Assemblies that had been established under the Government of India Act, 1935. The Constituent Assembly was composed roughly along the lines suggested by the plan proposed by the committee of the British cabinet, known as the Cabinet Mission.

According to this plan:

Each Province and each Princely State or group of States were allotted seats proportional to their respective population roughly in the ratio of 1:10,00,000. As a result the Provinces (that were under direct British rule) were to elect 292 members while the Princely States were allotted a minimum of 93 seats. 

The seats in each Province were distributed among the three main communities, Muslims, Sikhs and general, in proportion to their respective populations.

Members of each community in the Provincial Legislative Assembly elected their own representatives by the method of proportional representation with single transferable vote.

The method of selection in the case of representatives of Princely States was to be determined by consultation.
