Question

Given below are two statements: one is labelled as Assertion A and the other is labelled as Reason R Assertion A: Polygraph examination, also known as lie detection, is a psycho-physiological mode of the detection of deception in crime investigation process.
Reason R: Polygraph examination does not require the consent of the subject being investigated. In the light of the above statements, choose the most appropriate answer from the options given below:

• A. Both A and R are correct and R is the correct explanation of A.
• B. Both A and R are correct but R is NOT the correct explanation of A.
• C. A is correct but R is not correct.
• D. A is not correct but R is correct.

Hint:

Polygraph, Narco-analysis, and Brain Mapping tests require voluntary consent of the accused in India.

Answer 1

The Correct Option is C

Concept: Polygraph tests are scientific techniques used in criminal investigations to detect deception by measuring physiological responses.

Step 1: Evaluate Assertion A.
A polygraph records physiological changes such as blood pressure, respiration, and heartbeat during questioning. Hence, it is correctly described as a psycho-physiological method of deception detection. Therefore, Assertion A is correct.

Step 2: Evaluate Reason R.
In India, consent of the subject is mandatory before conducting a polygraph examination. The Supreme Court in Selvi vs State of Karnataka (2010) ruled that involuntary tests violate constitutional rights. Therefore, Reason R is incorrect.

Step 3: Conclude the answer.
Assertion A is true, but Reason R is false. Hence, the correct option is: \[ \boxed{\text{A is correct but R is not correct}} \]
