Explanation:

To determine the slopes of parallel lines, we recall the geometric definition: two non - vertical parallel lines have the same (identical) slope. Vertical parallel lines both have an undefined slope. The option "always 100" is incorrect as slopes of parallel lines don't have to be 100. "Always 0" is wrong because only horizontal parallel lines have a slope of 0, and there are other types of parallel lines (e.g., vertical or with non - zero slopes). "Opposites" is incorrect as that's not the property of slopes of parallel lines. "Opposite reciprocals" is the property of slopes of perpendicular lines, not parallel lines. So the correct option is "identical".

Answer:

C. identical
