The correct option is 1, 2 and 3 only.
Explanation
The "Objectives Resolution" was moved by Jawaharlal Nehru on December 13, 1946, and adopted by the Constituent Assembly on January 22, 1947. It laid down the fundamentals and philosophy of the constitutional structure, which later took the form of the Preamble to the Constitution of India.
Statement-wise Analysis:
- Statement 1 is Correct: The Resolution explicitly defined the aims and objectives of the Constituent Assembly, serving as a guiding framework for the drafting of the Constitution.
- Statement 2 is Correct: The very first clause of the Resolution declared the Assembly's firm and solemn resolve to proclaim India as an "Independent Sovereign Republic" and to draw up a Constitution for her future governance.
- Statement 3 is Correct: The Resolution contained specific provisions stating that "adequate safeguards shall be provided for minorities, backward and tribal areas, and depressed and other backward classes."
- Statement 4 is Incorrect: While the Resolution envisioned a federal basis (autonomous units with residuary powers), it did not "establish the exact federal structure immediately." It was a declaration of intent and principles. The actual federal details evolved significantly during the drafting process, especially after the partition became inevitable, shifting from the Resolution's initial idea of a weak centre (to accommodate the Muslim League) to the final Constitution's strong centre.
Key Takeaway:
The Objectives Resolution provided the philosophical foundation (later the Preamble) and broad principles for the Constitution but did not finalize or enact the detailed administrative or federal provisions instantly.
