Answer:
B. “the charges were laughable” (Paragraph 20)
Explanation:
Thes question refers to the article "A Child Of Slavery Who Thought A Generation" which tells the story of Anna Cooper.
She was, amongst other things, a principal and a teacher in first public high school for black students. Her work was amazing and very inspirational, which obviously bothered some people which led to a scandal ginned up against her.
The word "ginned up" means that something was started, agitated, increased or generated in a dubious manner and with dishonest purpose. This means that accusations were made only to throw dirt on her, without any factual evidence.
The sentence that best supports this is "the charges were laughable".
Although many prominent people stood in her defence, Cooper had to resign her principal's post due to the scandal and public pressure.
