Which type of conditioning is it if the unconditioned stimulus is presented before the neutral stimulus ends? a. backward b. trace c. concurrent d. delay?

I believe the answer is: B. Trace Conditioning

Trace Conditioning is a form of learning that's being done by associating conditioned stimulus and unconditioned stimulus within a temporal time gap. With this process, the conditioning would happen within a longer period compared to normal conditioning but would most likely to stay longer.

It would be around the egyptian area.
