From the figure;
The <em>top part of the mountain</em> is at an elevation of 264 units.
and from the hint the hikers are all at the same elevation; which again from the figure is given as 180 units.
So the difference in elevation for the hikers is: 264-180=<em><u>84</u></em> units.
Hence; the answer is Option: <em><u>A 84</u></em>
