The answer to this question depends on the given timeline. According to the question about the elephant population in Africa under the “Elephant Awareness”, the correct answer is letter A or 600,000 elephants. While it is correct, it is worthy to note that this answer is only applicable if we are to take into consideration the elephant population between the years 1980 and 1990; wherein the population declined from 1.3 million to only 600,000.
However, if we are to talk about the present time, the correct and most appropriate answer would be letter D or 400,000 elephants. This decline is because of poachers, one of the greatest threats in the elephant population in Africa. If this continues, it may decline even more and elephants may soon face extinction.
