The correct answer is B. Withheld treatment
Explanation:
The Tuskegee syphilis experiments were a set of controversial studies carried out in the U.S. between 1932 and 1972. In these studies, researchers enrolled hundred of black men, including men with syphilis (sexually transmitted infection) and healthy men with the promise of medical help. However, the real purpose was to observe the evolution of the disease and due to this, even when a cure was discovered around the 1960s the men were never treated. Indeed doctors participating in this study only gave placebos to patients and never explained to them they had syphilis or the real purpose of the study.
This implies, doctors only withheld appropriate treatment to syphilis suffers, which led to negative consequences including the transmission of the disease to the healthy population and the death of many participants due to lack of treatment.
