Answer:
not be reinforced
Explanation:
Discrimination training involves reinforcing a behavior in the presence of one stimulus but not others. There are two stimuli that are used to indicate this reinforcement. These are S Delta and SD.
The S-delta is the stimulus in the presence of which the behavior is not reinforced. The discriminative stimulus SD is the cue (stimulus) that is present when the behavior is reinforced.
So the correct answer is that the operant responding will not be reinforced when S Delta is present.
