That D.

It turned out to be 343,770 miles away from the observer. To appear 0.25° from the horizon it would have to recede to 687,540 miles. When I pointed out the miniscule angular size that a 26 mile diameter circle would have at those distances it was almost comical. It will likely come as no surprise that mathematics tend to make him rather upset.
