African Americans have lower survival rates for most cancers compared to other ethnic groups. These ethnic discrepancies are most likely due to​

A) ​social factors.
B) ​genetic factors.
C) ​biological factors.
D) ​racial discrimination.

Social factors, such as lower access to healthcare and higher poverty rates, have been shown to contribute to lower cancer survival rates in African Americans. While genetic factors and biological factors may play a role, there is currently more evidence supporting the impact of social determinants of health on cancer outcomes in this population. Racial discrimination may also contribute to these disparities, but it is likely mediated by social factors as well.
