Explanation: The phrase adverse impact or unintentional discrimination refers to the selection rate of a protected class being less than 80% of the selection rate of the highest group. In other words, if the selection rate of females is less than 80% the selection rate of males, there is an adverse impact on females by the hiring process. Answer choice A is the opposite of the correct definition of adverse impact, so it is incorrect. Answer choice B is close to the meaning of adverse impact - in a broad sense - but it is not specific enough to be correct. Answer choice C is also too broad, particularly because there is far more to the Uniform Guidelines on Employee Selection Process than just selection rate. And answer choice E is incorrect; while adverse impact might be interpreted as discrimination, it is not necessarily the direct result of discrimination.
