What is the version of the machine VVPAT used for voting in India?

Explanation

To supervise the prescribed election process and mechanism, the Constitution provides for the establishment of an independent body known as the Election Commission under Article 324. The use of Electronic Voting Machines has made the election system more transparent, simple, and convenient. For official verification of this transparency, the Election Commission uses the Voter Verified Paper Audit Trail (VVPAT). At present, the M3 version of the VVPAT machine is used by the Election Commission for voting. Hence, option (c) is the correct answer.
