Agencies studying discrimination in housing have experimentally proved that minority clients are often discouraged as prospective buyers of residential real estate and the antidiscrimination legislation of recent decades were only mitigating, rather than abolishing, inequality in housing practices.

B. In recent decades, the antidiscrimination legislation only mitigated, rather than abolishing, inequality in housing practices

C. that antidiscrimination legislation of recent decades has only mitigated, rather than abolished, inequality in housing practices

D. that, in recent decades, antidiscrimination legislation has only mitigated, rather than abolishing, housing practices inequality

E. that recent decades antidiscrimination legislation only were mitigating, rather than abolishing, housing practices inequality.

B. In recent decades, the antidiscrimination legislation only mitigated, rather than abolishing, inequality in housing practices - wrong, verbs with rather should be in the same form

C. that antidiscrimination legislation of recent decades has only mitigated, rather than abolished, inequality in housing practices - correct

D. that, in recent decades, antidiscrimination legislation has only mitigated, rather than abolishing, housing practices inequality - again verb forms not parallel.

E. that recent decades antidiscrimination legislation only were mitigating, rather than abolishing, housing practices inequality. - legislation is single, so were should be substituted for was

IMO C

That is required to make the sentence parallel with "that minority clients are often discouraged as prospective buyers of residential real estate".

C is the only choice where both verbs are also parallel
