Answer:
The correct answer is A.
Step-by-step explanation:
The Brownsville Affair falsely accused African American soldiers. They were given dishonorable discharge.
The Brownsville Affair happened in 1906. One white man was shot and killed and another shot and wounded. Even though white commanders said the soldiers had all been in their barracks, the African American soldiers were still dishonorably discharged.
It wasn't until after most of them were dead that they were given honorable discharged and provided a little compensation.
Thus, the best answer here is A.
Answers B, C, and D are not true.
