The correct option is 1 and 3 only.
Explanation
The composition of the Constituent Assembly underwent significant changes following the partition of India and the enactment of the Indian Independence Act, 1947. The withdrawal of members belonging to the areas included in Pakistan necessitated a restructuring of the Assembly's strength and representation.
Statement 1 is Correct:
Originally, the total strength of the Constituent Assembly was fixed at 389. However, after the partition, the members of the Muslim League from the areas included in Pakistan withdrew from the Constituent Assembly of India. Consequently, the total strength of the Assembly was reduced to 299. Of these, 229 members represented the British Indian Provinces, and 70 members represented the Princely States.
Statement 2 is Incorrect:
The Congress party held an overwhelming majority in the Constituent Assembly. It occupied approximately 82 % of the seats in the Assembly after the partition. It did not hold less than fifty % of the seats.
Statement 3 is Correct:
The Constituent Assembly was constituted to be representative of various sections of Indian society. According to standard political science records, the Assembly included twenty-eight members from the Scheduled Castes.
Key Takeaway:
The Indian Independence Act, 1947, reduced the Constituent Assembly's strength to 299, wherein the Congress held a dominant majority (82%), and the body maintained representation from diverse groups, including 28 members from the Scheduled Castes.
