The correct answer is B the decision in Reed v. Reed was the beginning of a series of decisions that marked a shift in how the Court looks at sex discrimination

Explanation:

The Reed v. Reed  was a law case in 1971 in which the Supreme Court in the United States decided the executor of an estate could not be chosen just according to its gender, after Sally and Cecil Reed got divorced and Cecil (the man) was chosen as the administrator of the state of their son as a result of Idaho Code preference for males in this kind of cases. Later, after the Supreme Court studied the case it was decided that this preference was unconstitutional and other codes and laws were studied as a result. Thus, after the Reed v. Reed case different codes around different states that were based on gender were modified and sex discrimination in law was widely studied and considered to avoid sex-based discrimination.
