The answer is: A
Explanation
Answer: A - Yadavindra Singh
Explanation:
When PEPSU (Patiala and East Punjab States Union) was formed on 15 July 1948 by merging 8 Phulkian and other princely states, Maharaja Yadavindra Singh of Patiala was appointed its first Rajpramukh (constitutional head).
This was a natural choice since Patiala was the largest and most dominant state in the union, and Yadavindra Singh was the most powerful ruler among the merged states.
PEPSU existed as a separate state until 1956 when it was merged into Punjab under the States Reorganisation Act.
The 8 states that formed PEPSU:
- Patiala
- Nabha
- Jind
- Kapurthala
- Faridkot
- Malerkotla
- Nalagarh
- Kalsia
Why other options are wrong:
- Jagatjit Singh - Was the Maharaja of Kapurthala, a member state of PEPSU but not its Rajpramukh.
- Gian Singh Rarewala - Was actually the Chief Minister of PEPSU, not Rajpramukh.
- Raghbir Singh - No significant PEPSU leadership role.
The critical trap here:
Candidates confuse Rajpramukh (constitutional/ceremonial head) with Chief Minister (executive head). Rarewala as CM is frequently confused with Yadavindra Singh as Rajpramukh.
