Choose the correct answer from the given options:

A, D and E

The correct answer is Option 2 - A, D and E

The correct statements are:

A) Elections for 15th Lok Sabha were held in 2009.
D) Narendra Modi led the NDA governments formed in the 17th Lok Sabha elections.
E) The BJP again emerged victorious with 303 seats of its own in 2019 Lok Sabha election.

Correction in the incorrect statement:

B) Bhartiya Janata Party declared Narendra Modi as its Prime Ministerial candidate in September 2013.

C) Despite single-party majority of its own, the BJP did choose to form the NDA government with its coalition partners in 16th Lok Sabha.

The Congress led UPA government completed its term despite Left parties withdrawing the support in July 2008 on the issue of Indo- US nuclear deal. Elections for 15th Lok Sabha were held in 2009. Results witnessed a rise in the number of seats (from 145 in 2004 to 206 in 2009) of the Indian National Congress (INC) and Congress led UPA Government. Dr. Manmohan Singh was sworn as Prime Minister for the second term, heading the coalition government of UPA again.

Bhartiya Janata Party declared Narendra Modi (then the Chief Minister of Gujrat) as its Prime Ministerial candidate in September 2013. BJP under the leadership of Narendra Modi got a clear majority in 16th Lok Sabha elections held in 2014. BJP won 282 seats on its own, becoming the first party to gain single party majority after 30 years. Despite single-party majority of its own, BJP did choose to form the NDA government with its coalition partners.

Year 2014 was a proverbial watershed moment of Indian politics. Narendra Modi led NDA government rapidly took decisions in social sector, foreign policy and economic policy. The BJP again emerged victorious with 303 seats of its own in 2019 Lok Sabha election. Even when BJP is getting full majority, the recognition of coalition politics is still relevant. Thus, the party system has now changed almost dramatically from what it was till the seventies.
