The correct answer is D.
Sylvia Mendez is an American writer and civil rights activist of Mexican-Puerto Rican heritage.
At the age of eight, she played an important role in the Mendez v. Westminster case which was a landmark desegregation case of 1946.
When she was growing up in California, Hispanics were not allowed to attend Whites only schools. Mendez was sent to a so called Mexican school, a decision her parents opposed. They filed a law suit in the local federal court. Sylvia Mendez was asked to prove she could speak and understand the English language.
Their case was a success and it paved way to the end of racial segregation of schools in the United States.
