The correct answer is B. The expansion of individual rights, particularly where personal liberties were at issue.
This statement is evident from the Warren Court based on two major rulings including:
1) Brown vs. Board of Education- This case effectively ended segregation in American public schools. This court overturned the Plessy vs. Ferguson case that established the concept of separate but equal. This ruling allowed for African-American citizens to receive a higher quality education.
2) Miranda vs. Arizona- This case resulted in the Miranda warning we know today. The Warren court ruled in favor of Miranda, establishing the legal precedent that officials of the law must make the citizen aware of their rights upon arrest.
