Explanation:

• The EVMs have the NOTA option at the end of the candidates' list. Earlier, in order to cast a negative ballot, a voter had to inform the presiding officer at the polling booth. A NOTA vote doesn't require the involvement of the presiding officer. Before the NOTA option came in existence, people casting negative votes were required to enter their names in a register and cast their vote on a separate paper ballot.
• Under Section 49 (O) of the Conduct of Elections Rules, 1961, a voter could enter his electoral serial number in Form 17A and cast a negative vote. The presiding officer would then put a remark in the form and get it signed by the voter. This was done to prevent fraud or misuse of votes.
• This provision was, however, deemed unconstitutional by the SC as it did not protect the identity of the voter.. Hence All the statements are not correct.
