The true statement for all parallel lines is:
**A. Parallel lines have the same slope.**
Parallel lines never intersect and, therefore, must have the same slope. The other options relate to different types of lines: negative reciprocals apply to perpendicular lines (option B), undefined slopes correspond to vertical lines (option C), and a slope of zero applies to horizontal lines (option D).
