Answer:
Among the options given on the question the correct answer is option B.
The Supreme Court overturning the doctrine of "separate but equal".
Explanation: The Sweatt v. Painter case of US Supreme Court 1950 was a landmark case which was a starting of the overturning of the doctrine of 'separate but equal' by the US supreme court.
The Jim Craw low which segregated the public facilities on the basis of race dominated many years in the US. But after World War ll there was a raise against this law for equal rights. Because the 'separate but equal' principal was not applied in the reality. There was substantial difference between white and African American facilities.
Many of the African American filed law suit against the segregation law in different circumstances. The Sweatt vs Painter law suit ruling by Supreme court ordered the Texas Law school which was allocated for white Americans,to admit Mr Sweatt who was an African American .This ruling paved the way of the Supreme Court overturning the doctrine of 'separate but equal' and had an impact on the Brown vs Board case in 1954.
