Weber's Law states that the smallest change in a stimulus that can be detected (the difference threshold) is proportional to the intensity of the original stimulus. This means that the greater the initial stimulus intensity, the larger the change in that stimulus must be in order for an individual to notice a difference.

For example, if you are holding a light weight, a small increase might be noticeable, but if you are holding a very heavy weight, a much larger increase is necessary for you to perceive the difference. This principle illustrates that the amount of change needed to notice a difference is not constant but depends on the original intensity of the stimulus, making the correct choice regarding Weber's Law the relationship between the original stimulus intensity and its corresponding threshold.
