योग्य कथन/ने ओळखा (संसदेचे दुहेरी सदस्यत्व).
अ. जर एका सभागृहातील सदस्य दुसऱ्या सभागृहात निवडून आला तर त्याची जागा पहिल्या सभागृहात रिकामी होते.
ब. जर एखादी व्यक्ती सभागृहातील दोन जागांवर निवडून आली तर त्याने त्यापैकी एक जागेचा पर्याय निवडावा अन्यथा दोन्ही जागा रिक्त होतील.

The correct answer is Option C (Both A and B).

Key Points:
• Provisions Regarding Double Membership of Parliament (RPA 1951):
• Under the Representation of the People Act, 1951 (Section 67–70) and Article 101 of the Constitution, a person cannot simultaneously be a member of both Houses of Parliament or hold two seats in the same House:
• 1. Statement A is correct: If a sitting member of one House is subsequently elected to the other House, their seat in the first House automatically becomes vacant.
• 2. Statement B is correct: If a person is elected to two seats in a single House (e.g., contesting from two Lok Sabha constituencies and winning both), they must exercise an option choosing one seat within the prescribed time limit. If they fail to do so, both seats become vacant.
• 3. If a person is elected to both Houses simultaneously, they must intimate within 10 days which House they wish to serve; otherwise, their Rajya Sabha seat becomes vacant.
• Therefore, both statements A and B are correct.
• Hence, Option (3) Both A and B is the correct answer.
• Key Takeaway: Sitting member elected to other House vacates first seat; winning two seats without choosing vacates both seats.
