Final answer:
A Polygraph Test is used to measure physiological reactions that may indicate whether a person is being truthful or not, but its accuracy is debated. The correct option is B.
Step-by-step explanation:
Testing a guilty person with facts to elicit strong emotional responses and corresponding physiological arousal is a procedure known as a Polygraph Test. The device measures indicators such as heart rate, respiration rate, and sweating, to infer the truthfulness of the subject's responses.
While commonly used in law enforcement and sometimes in the hiring process, the accuracy of polygraphs is debated, as physiological responses are not uniquely tied to dishonesty, and other factors can cause similar reactions.
