How did rosa parks require both physical and moral courage when she refused to give up her seat on a montgomery bus?

In a time period where the majority of society were angry white people showed her physical courage. She knew what she was doing was going to get her in trouble yet she did it anyways because of the unjust treatment her race faced which can be seen as her moral courage. Also, it caught the world's attention & that attention was finally more focused on the treatment blacks endured. :)

Its is d. because i did it
