B) conditioned
C) backward
D) explicitly unpaired

This scenario describes explicitly unpaired inhibition, where the conditioned stimulus (CS) and unconditioned stimulus (US) are presented at irregular and nonoptimal timing intervals, leading subjects to learn that the CS predicts the absence of the US. This is different from procedures that involve pairing the CS and US in a way that establishes a predictive relationship for the occurrence of the US.
