Which of these best describes the official status of African Americans in the United States during World War I

"Separate but equal" best describes the official status of African Americans in the United States during World War I.

Explanation:

The supreme court of United States permitted states to segregate people of color by applying earlier laws on civil rights, when African Americans knocked at supreme court to protect their rights under the constitution.

A new Louisiana law in 1890 needed railroads to give "equal but separate accommodations on the basis of colored races" this blasted the New Orleans' black community therefore "Plessy v. Ferguson" case got stand and decision of supreme court came as "separate but equals". Plessy is commonly refereed as one of the worst decisions in the U. S. History of the Supreme Court. Later series of decisions came which overruled the "separate but equal" as found unconstitutional like "1954 case Brown v. Board of Education".
