Minority groups signed up for segregated units like the Tuskegee Airmen and Navajo Code Talkers for which of the following reasons?

B. To show their equality to the nation during WWII.

Explanation:

Minority groups have been fighting for recognition in American history for a long time and this is not without merit because time and time again they have contributed to American history like European descendants.

One such time was during the second world war where African Americans formed the Tuskegee Airmen who flew many successful missions in the war and the Navajo Code Talkers who came up with a code so complex that the Japanese could not break it. Both of these groups did this to show that they were just as American as other groups.
