Which of these statements regarding corporate affirmative action policies would Tom L. Beauchamp most agree with in Affirmative Action Goals in Hiring and Promotion?
 
  a. Corporate affirmative action policies should be voluntary since it is outside
  the scope of government control to dictate hiring policies by corporations
  outside of clearly egregious cases of discrimination.
  b. There is reason to believe that corporate affirmative action policies may
  be in line with best hiring strategies since there is evidence to suggest
  hidden or unconscious discrimination may prevent companies from hiring
  the best candidates.
  c. The government should dictate corporate affirmative action policies for all
  corporations employing more than a certain number of employees to
  ensure fairness.
  d. Discrimination plays such a minor role in corporate hiring that corporate
  affirmative action policies are no longer required.
