A software company starts to give monthly polygraph tests to all of its employees to catch anyone who may be selling proprietary information to other companies. This approach is unlikely to be very successful because a lie detector test:
A) measures arousal, not lying
B) measures subjective perceptions, not objective truths
C) tracks the brain areas involved in a response but not the processing in those areas
D) identifies brain regions that are too large to identify lying
