Which accurately describes apartheid? a. it was started by nelson mandela. b. it kept the majority white population in power in south africa. c. it ended in the early 20th century. d. it ended due to international pressure.

Nelson Mandela helped end apartheid, so A is incorrect. B would be right, but the white population is the minority in South Africa, not the majority. It ended in 1991, so C is not right. This leaves us with D, the correct answer. I hope this helps!
