The correct option is 3 only.
Explanation
Under the Constitution of India, the Parliament consists of the President, the Council of States (Rajya Sabha), and the House of the People (Lok Sabha). A fundamental distinction between the two Houses is their tenure and dissolution status.
Statement-wise Analysis:
- Statement 1 is Incorrect: The Rajya Sabha is not dissolved every six years. While the term of office for an individual member is six years, the House itself is a continuing chamber. One-third of its members retire every second year, and these vacancies are filled by fresh elections and presidential nominations.
- Statement 2 is Incorrect: A proclamation of National Emergency does not lead to the dissolution of the Rajya Sabha. While the duration of the Lok Sabha may be extended by Parliament by law for a period not exceeding one year at a time during an emergency, the Rajya Sabha remains unaffected as a permanent body.
- Statement 3 is Correct: According to Article 83(1) of the Constitution, the Council of States shall not be subject to dissolution. It is designed as a permanent house to ensure legislative continuity.
Key Takeaway: The Rajya Sabha is a permanent body and is never dissolved; only its members serve a fixed tenure of six years, with one-third retiring biennially.
