The correct answer is: A. 11 December.
The International Day of Remembrance of the Victims of Slavery and the Transatlantic Slave Trade is observed on 25 December each year. It was established by the United Nations General Assembly in 2007 to commemorate the victims of slavery and the transatlantic slave trade. The day is also an opportunity to raise awareness of the lasting impact of slavery and the transatlantic slave trade on individuals, families, and communities around the world.
The transatlantic slave trade was a brutal and dehumanizing system that enslaved millions of people from Africa and transported them to the Americas. The trade began in the 15th century and continued for over 400 years. During that time, an estimated 12 million Africans were enslaved and transported to the Americas. The transatlantic slave trade had a devastating impact on Africa, both economically and socially. It also had a profound impact on the Americas, where it created a system of racial inequality that continues to this day.
The International Day of Remembrance of the Victims of Slavery and the Transatlantic Slave Trade is an important opportunity to remember the victims of this horrific system and to reflect on its legacy. It is also a time to recommit ourselves to the fight against racism and discrimination.
The other options are incorrect because they are not the dates on which the International Day of Remembrance of the Victims of Slavery and the Transatlantic Slave Trade is observed.
