It's not Africa because that continent does not own any other territories so it resigns only in the southern hemisphere. Oceania is not a continent so it is definitely not the answer. Asia cross to both the northern and southern hemisphere. The claim the title because in their name they own several out reaching lands and oceans. For example the dead sea. So they are not limited to their continent but reach(own) "The highest and lowest points".
Therefore your answer should be D. Asia
