A.
Explanation:
Executive Order 9981 is an executive order that was enacted to end the discrimination in the armed industry.
The order was signed by President Harry S. Truman on July 26, 1948. Before this executive order, there was discrimination between the white army man and blacks. Blacks were required to wait for four years after being qualified before entering the combat whereas whites were allowed into combat within a few months of being qualified.
So, to put this discrimination to an end, this Executive Order was signed. According to this order, no man in armed or defence industry shall be discriminated based on national origin, gender, or race.
