When a CS has become a conditioned inhibitor, researchers assume that to the subject, the CS now signals "no US." Which evidence best supports that conclusion?
A) A conditioned inhibitor conditions more slowly than a preexposed CS.
B) A conditioned inhibitor will suppress a CR to a different CS conditioned with the same US.
C) A preexposed (i.e., not novel) CS will interfere with responding to a different CS.
D) The inhibitor acts like a preexposed CS, which indicates that nothing particular will occur and thus produces no behavior.

A conditioned inhibitor, when paired with another CS that predicts a US, can suppress the conditioned response (CR) to that CS. This suppression suggests that the conditioned inhibitor signals the absence of the US, thereby inhibiting the response that would otherwise be elicited by the CS associated with the US.
