Answer: [Option (c) Only three statements]
Explanation: Statement 1, 2, and 3 are correct.

The Tamil Nadu government used various officials to present the truth and contain the spread of fake news. However, statement 4 is incorrect. Disinformation campaigns have the potential to manipulate social and political outcomes, and this issue should be ranked high in terms of potential to destabilize democratic institutions.
