Which statement is the BEST response about a scientific opinion on the use of polygraphic evidence?

A) "Although they are used widely, polygraph results are not particularly reliable."
B) "The APA endorses their use."
C) "On average, 50 out of 100 truths are categorized as lies."
D) "Most courts admit evidence from polygraphs in criminal trials."

Polygraph tests, commonly known as lie detector tests, have been widely criticized for their reliability and accuracy. The scientific consensus is that while they can sometimes provide useful information, their results are not reliable enough to be considered definitive evidence. This is because polygraphs measure physiological responses that can vary for reasons unrelated to lying, such as nervousness.
