The correct answer is A.
Since she grow up in apartheid-era South Africa, Hilary Kromberg Inglis witnessed discrimination first-hand.
She could see how black men were thrown out of her white neighborhood daily, and she witnessed how South African authorities did not allowed her uncle, who was banned from the country for speaking against the apartheid, to say his final goodbye to his dying father.
This led her to join the fight for justice and equallity. She was a white woman fighting for black rights, and she herself suffered many injustices because of that.
