B Correct answer
Explanation

Dimensions are conformed when they are either identical across multiple fact tables (same attributes and keys) OR one is a subset of another (grain coarser but same meaning). This conformance enables drill-across operations. Option A is wrong because conformed dimensions are intentionally alike, not different. Option C is incorrect because conformance is about semantic consistency, not mathematical comparability.
