Which concept describes the property that if A is related to B, then B is related to A?

• A. Transitivity
• B. Symmetry
• C. Reflexivity
• D. Stimulus Equivalence

Answer: (B)

Symmetry describes a relationship that can be reversed without changing its truth value: if A is related to B, then B is related to A. This bidirectional nature is what the scenario is asking about. For example, in a friendship relation, if A is friends with B, then B is friends with A. Transitivity is about chaining relationships (A related to B and B related to C implies A related to C). Reflexivity is about every element relating to itself (A relates to A). Stimulus equivalence is a broader behavioral concept that involves learned relations among stimuli, often including symmetry as part of the cluster of properties but not defined by the simple statement given.
