Explanation:

The Electronic Voting Machine (EVM), the replacement of the ballot box is mainstay in the electoral process. First conceived in 1977 in the Election Commission. o First time use of EVMs occurred in the general election in Kerala in May, 1982; however, the absence of a specific law prescribing its use led to the Supreme Court striking down that election. Hence statement 3 is correct. o Subsequently, in 1989, the Parliament amended the Representation of the People Act, 1951 to create a provision for the use of EVMs in the elections (chapter 3). A general consensus on its introduction could be reached only in 1998 and these were used in 25 Legislative Assembly constituencies spread across three states of Madhya Pradesh, Rajasthan and Delhi. • Voter Verifiable Paper Audit Trail (VVPAT) is an independent system attached with the Electronic Voting Machines that allows the voters to verify that their votes are cast as intended. When a vote is cast, a slip is printed on the VVPAT printer containing the serial number, name and symbol of the candidate and remains exposed through a transparent window for 7 seconds. Thereafter, this printed slip automatically gets cut and falls in sealed drop box of the VVPAT. o In the 2014 Lok Sabha polls, VVPATs were used in eight constituencies and in the 2019 Lok Sabha polls, VVPATs were used in all the constituencies. Hence statement 2 is correct. • NOTA, or "None of the Above", is the option which enables the voter to officially register a vote of rejection for all candidates who are contesting. If a voter chooses to press NOTA it indicates that the voter has not chosen to vote for any of the party. • On 27 September 2013, the Supreme court of India ruled that the right to register a "none of the above" vote in elections should apply, while ordering the Election Commission to provide a button for the same in the electronic voting machines. • The ECI introduced a particular symbol for ‘None of the Above’ option to allow the voters to exercise NOTA. This symbol appears in the last panel on all Electronic Voting Machines (EVMs). • In Lok Sabha elections, the None of the Above or NOTA option was first used in 2014. Hence statement 1 is correct.
