Read each of the following two statements, Assertion (A) and Reason (R). And indicate your answer using the codes given below :

UGC NET - 2013,
Answer: C
The assertion is true and the reason is false: (A) is true, but (R) is false.
Polygraph tests are used to infer truthfulness although they are not infallible (A). The assumption behind them is that lying is accompanied by greater sympathetic arousal, shown by higher heart rate, blood pressure, breathing and skin conductance, not by lesser activation. So the reason as stated is false.
Hence the options saying both are true, or the assertion is false, do not fit.
