Answer- C
1)The International Day of Commemoration in Memory of the Victims of the Holocaust, also known as International Holocaust Remembrance Day, is observed every year on January 27th. The United Nations has chosen the theme of "Memory, Dignity and Justice" to guide its Holocaust remembrance and education efforts in 2022. The purpose of this day is to commemorate the tragic events of the Holocaust that took place during World War II.
2)During World War II, Nazi Germany and its collaborators committed genocide, systematically murdering around six million European Jews, which constituted about two-thirds of the Jewish population in Europe, between the years of 1941 and 1945. In 2005, the United Nations established this day as an official commemoration for the victims of the Nazi regime and to encourage Holocaust education globally.
