The correct answer is option 3: 2002. The Prevention of Terrorism Act (POTA) was enacted in the year 2002. POTA was a law passed by the Indian government with the aim of combating terrorism. It provided law enforcement agencies with additional powers to investigate and prevent acts of terrorism. The act contained provisions for the detention, arrest, and interrogation of individuals suspected of being involved in terrorist activities. POTA was controversial due to concerns about potential misuse and violation of human rights. It was eventually repealed in 2004 after criticism that it was being misused to target innocent individuals. Overall, the enactment of POTA in 2002 was a significant event in India`s efforts to combat terrorism.
