In the Analytical Hierarchy Process (AHP), the matrices used for pairwise comparisons (options A, C, and D) inherently have 1s along their diagonals because each element is compared with itself, resulting in a ratio of 1. The exception is the weighted priorities for the criteria matrix (option B), which does not follow this structure as it represents the outcome of synthesizing the comparisons, not the comparisons themselves.
