Correct Option (B)
- Pair 1: Bharatiya Jana Sangh – Dr. Shyama Prasad Mukherjee. This pair is correctly matched. Dr. Shyama Prasad Mukherjee founded the Bharatiya Jana Sangh in 1951 and served as its first president.
- Pair 3: Congress for Democracy – Jagjivan Ram. This pair is correctly matched. Jagjivan Ram, along with H.N. Bahuguna and Nandini Satpathy, founded the Congress for Democracy in 1977 after leaving the Indian National Congress during the Emergency.
Incorrect Options
- Pair 2: Socialist Party – C. Rajagopalachari. This pair is incorrectly matched. The Socialist Party was primarily led by figures such as Ram Manohar Lohia and Jayaprakash Narayan. C. Rajagopalachari was known for his opposition to socialist policies and was not associated with the Socialist Party.
- Pair 4: Swatantra Party – Acharya Narendra Dev. This pair is incorrectly matched. The Swatantra Party was founded by C. Rajagopalachari in 1959. Acharya Narendra Dev was a prominent leader of the Congress Socialist Party, not the Swatantra Party.
Based on the analysis, only two pairs (1 and 3) are correctly matched. Therefore, options stating 'Only one', 'Only three', or 'All four' are incorrect.
