Answer:
The Equator
Explanation:
The Equator is found at 0° latitude. 0° latitude divides the Earth into two equal hemispheres known as the north and south hemispheres.
I believe the answer is E. d41 because it goes a11, A12, b21, B22, c31, C32, then it goes lowercase d41 and then the next one is going to upper case D42.
Hope this helps.
