Lines of latitude are all parallel to the equator and to each other. Just like parallel lines on a flat surface, no two of them ever touch. So 'A' and 'B' are correct.
Lines of latitude are parallel to the equator and never touch. Therefore, both options 'A' and 'B' are correct, making 'D' the right answer. Lines of latitude maintain a constant distance from each other, similar to parallel lines on a flat surface.
