Parallel shift alignment means the axes or centerlines of the two shafts run in the same direction and are parallel to each other, but they are offset from one another rather than sharing the same line. That makes the statement about the centerlines being parallel the true characterization of this alignment type.

Other options describe different ideas: having centerlines perpendicular would indicate angular misalignment, not parallel shift; diameter size and rotation speed are separate mechanical properties, not definitions of alignment.
