Answer:
Point A to Point B at 10°N has the longest distance.
Step-by-step explanation:
A is correct because this option represents these points as being the closest to the Equator, where Earth is the widest, thus the distance between them is the longest.
B is not correct because these points are further away from the Equator, so the distance between them will be longer.
C is not correct because by being slightly further away from the Equator than option A, they have a slightly longer distance between them as well.
D is not correct because there can not be two points at the Pole itself, but just one point, and even if there were two just next to the Pole they would have been very close to each other.
