Why is the EVM checked before polling starts at a booth?

To ensure that the machine is working properly

Correct answer: A. An EVM is checked before polling so that officials can confirm that it is functioning properly and is ready to record votes. Polling is the stage when eligible voters cast their votes, while counting happens later. A pre-poll check can reveal technical problems before voters begin using the machine and helps the process run smoothly. It also supports confidence that votes will be recorded as intended, although a check by itself is only one part of a free and fair election. Option A is correct because it states the practical purpose of the check. Option B is wrong because speeches belong to campaigning, not machine testing. Option C is wrong because a voter's age is determined from official records, not changed by an EVM. Option D is wrong because the purpose is reliable voting, not hiding results. Memory cue: check before voting means readiness and reliability; counting comes after polling.
