Correct option is C
The correct answer is: (c) Kerala
Electronic Voting Machines (EVMs) were used for the first time in India in 1982 in Kerala.
This trial occurred during the by-election in the Parur Assembly Constituency.
Though the use was later stayed by the Supreme Court, this event marks the first practical use of EVMs in the country.
The case led to legal changes allowing EVM usage by amending the Representation of the People Act, 1951 in 1989.
The full-scale adoption of EVMs started only after 1998, and they became universal by the 2004 General Elections.
First EVM trial: 1982, Parur, Kerala.
EVMs were manufactured by BEL and ECIL.
Legal backing was provided in 1989 through amendments.
First General Election use: 1998, selected constituencies.
EVMs became universal across India in 2004 Lok Sabha polls.
VVPATs were introduced in 2013 to increase transparency.
