The answer is: B) the placebo effect

Explanation:

The placebo effect occurs when people experience a benefit after an inactive substance or treatment is administered to them. The Hawthorne Experiment led to a variation of the placebo effect which is called the Hawthorne Effect.

The Hawthorne Effect occurs when the study subjects respond to the mere attention paid to them by the study personnel. The study subjects react positively just because they are being part of an experiment.
