On. "We had been studying the Constitution in Miss Nesbitt's class. I knew I had rights. . . . I was thinking, Why should I have to get up just because a driver tells me to, or just because I'm black?" Colvin said.

Which is the best paraphrase of the excerpt?

Colvin explained that after studying the Constitution at school, she felt that her rights were being violated. She questioned why she should have to get up if she had paid her fare.
She had been studying the Constitution and knew that she did not have to get up from her seat just because she is black.
After studying the Constitution, I knew I had rights and I did not have to give up my seat for anyone just because of the color of my skin.
Colvin knew she had rights because she had studied the Constitution in Miss Nesbitt's class. And so, she began to wonder why she was being treated so unfairly.
