Final answer:
The exact percentage of African American physicians and dentists produced by Tougaloo College is not provided in the reference materials. Therefore, an accurate choice cannot be determined without further specific data.
Step-by-step explanation:
Tougaloo College, which is a private, historically black, liberal arts college, has made a significant impact in the state of Mississippi by producing a substantial percentage of African American professionals. While the provided text does not specify the exact percentage of African American physicians and dentists produced by Tougaloo College, it outlines the general progress and contribution of historically black colleges and universities (HBCUs) toward the education and professional qualification of African Americans during the post-emancipation and reconstruction periods. As an instructor, without the precise data pertaining to Tougaloo College's contribution to the medical and dental fields in Mississippi, one cannot accurately answer the multiple-choice question. Therefore, the student should be directed to seek specific statistical information regarding Tougaloo College's alumni in those fields which might be available through the college's official publications or state medical and dental associations.
