The correct answer is D. The reason those angles all represent the same angle is because a full rotation around the unit circle is equal to 2 pi. When you give 2 pi a common denominator of 5, it becomes (10 pi)/5. Then you just add (10 pi)/5 to the previous quantity (4 pi)/5 to get (14 pi)/5. The same goes for (24 pi)/5.
