01 Why is an EVM sealed after polling?
Answer and explanation
Correct answer: A. To prevent tampering and secure the votes
Explanation: The correct answer is A: sealing helps prevent tampering and secure the recorded votes after polling. Once voting closes, the machine and related records must be protected until the authorised counting process. A seal makes unauthorised opening or interference easier to detect and supports a documented chain of security. This helps protect the integrity of the election and public confidence in the result. Option B is wrong because sealing does not extend polling time; it normally follows the close of polling. Option C is wrong because a seal cannot add voters or votes. Option D is wrong because the purpose is to prevent unauthorised alteration, not to change a declared result. Memory cue: seal means secure and detect interference, not change the result.
