D) ensuring white governments stayed in power

The one role that the military had across the South during Congressional Reconstruction was that of forcing states to ratify the Fourteenth Amendment.

Explanation:

Even after the civil war ended, a few states in the South were hesitant towards accepting the abolishment of slavery. President Abraham Lincoln authorized the military to make use of coercion to get the Fourteenth Amendment ratified from the leaders of the states that were hesitant to do so by themselves. The military can be said to have succeeded as the Fourteenth Amendment was ratified by all the states before 1869.
