The correct answer is C. 7 December.
World Human Rights Day is observed on 10 December every year. It is a day to celebrate the Universal Declaration of Human Rights, which was adopted by the United Nations General Assembly on 10 December 1948. The Declaration sets out the fundamental human rights and freedoms to which all human beings are entitled, regardless of race, sex, nationality, ethnicity, language, religion, or any other status.
The Universal Declaration of Human Rights is a milestone document in the history of human rights. It was the first international instrument to set out a comprehensive list of human rights and freedoms. The Declaration has been translated into more than 500 languages and is the most widely translated document in the world.
World Human Rights Day is a time to reflect on the progress that has been made in the promotion and protection of human rights, and to recommit to the ideals of the Universal Declaration of Human Rights. It is also a time to call attention to the many challenges that remain, and to urge all people to work together to create a world where all human rights are respected and protected.
The other options are incorrect because they are not the dates on which World Human Rights Day is observed.
