Assertion: Charan Singh successfully completed 5 years as the Prime Minister of India after the Janata Party won the 1977 elections.
Reason: The Congress Party lent its support to the government headed by Charan Singh after the failure of the government headed by Morarji Desai.
Answer & explanation
Correct answer: option 3
The Janata Party split and the government which was led by Morarji Desai lost its majority in less than 18 months. Another government headed by Charan Singh was formed on the assurance of the support of the Congress party. But the Congress party later decided to withdraw its support with the result that the Charan Singh government could remain in power for just about four months. Fresh Lok Sabha elections were held in January 1980 in which the Janata Party suffered a comprehensive defeat, especially in north India where it had swept the polls in 1977.
