Answer :
The Nazi plan termed the 'Final Solution' aimed at the mass extermination of Jews and was discussed and put into motion at the Wannsee Conference in January 1942. The correct option is(3).
The Final Solution was the Nazi regime's plan to exterminate the Jewish population in Europe. This genocidal policy was formally addressed at the Wannsee Conference, which took place in January 1942. At this conference, senior German civil servants and Nazi officials conceived and laid the groundwork for the systematic murder of Europe's Jewish community, which would later result in the deaths of over six million Jews during the Holocaust.
German officials orchestrated methods such as working the Jews to death, starving them, or killing them in extermination camps. Methods of murdering included mass shootings, gas chambers, and other systematic means. The decision to move from deportation and forced emigration to systematic murder marked a grim escalation in the Nazis' approach toward achieving a Judenrein (Jew-Free) Europe, and the Wannsee Conference was a pivotal moment in this shift. The correct option is(3).
