The correct answers are C) members of Congress and legislature and D) judges and justices.
The positions of power and influence that would benefit from the inclusion of diverse members are the members of Congress and legislature and judges and justices.
Congress would benefit so much with members that do not think the same. To create laws that benefit the most, diversity is key because different backgrounds, belief systems, education, race, culture, only increases the possibility of better laws for the country. The same happens with the Court, judges, and judicial. If the judicial system has diversity in thinking and perspective, judges and justices are going to have a broader mind to understand and resolve issues impartially.
