A critical prediction of the stimulus substitution model is that the
A) properties of the CS (e.g., pulsed light and pulsed shock) must be similar to those of the US.
B) CR and the UR must resemble each other (e.g., CR is eyeblink when UR is eyeblink).
C) CS must precede the US and be contiguous in time and space.
D) CS must modulate the form of both the CR and the UR.

The stimulus substitution model posits that the conditioned stimulus (CS) becomes a substitute for the unconditioned stimulus (US), leading to the conditioned response (CR) being similar to the unconditioned response (UR). This model suggests that through conditioning, the organism learns to respond to the CS in a manner similar to how it responds to the US, hence the CR and UR should resemble each other.
