This question was cancelled (#) in the official MPSC final answer key.

Key Points:
• Formation of Janata Party (1977 Elections):
• The Coalition / Merger: In early 1977, following the withdrawal of Emergency, several opposition parties merged under the leadership of Jayaprakash Narayan and Morarji Desai to form the Janata Party.
• Core Merging Constituents: The alliance included Bharatiya Lok Dal (BLD led by Charan Singh), Bharatiya Jana Sangh (led by Atal Bihari Vajpayee and L. K. Advani), Indian National Congress (Organization) (Congress-O), and the Socialist Party (formed from Praja Socialist / Samyukta Socialist factions).
• Discrepancies: Congress for Democracy (CFD led by Jagjivan Ram) fought in alliance and merged later, while 'Congress (S)' (Urs/Sharad Pawar faction) formed only in 1978 after the 1978 split. Due to terminological errors in options, MPSC CANCELLED (#) this question in the Final Answer Key.
• Key Takeaway: Janata Party in 1977 was formed by the merger of BLD, Jan Sangh, Congress (O), and Socialists. [Cancelled by MPSC #]
