The correct option is B
Criminals were marked with inverted triangles of green, political prisoners with red, "asocials" (including Roma, rebels, vagabonds and other groups) with black or, in the case of Roma in some fields, Brown. Homosexuals were identified with pink triangles and Jehovah's Witnesses with purple ones. The non-German prisoners were identified with the first letter of the name of their native country in German, which was sewn on their badge. The two triangles that formed the Jewish star's insignia were yellow, unless the Jewish prisoner was included in any of the other categories of prisoners. Jewish political prisoners, for example, were identified with a yellow triangle under a red triangle.
