White southerners who helped the new republican governments in the south were referred to by the derogatory term Scalawag.

Option D

Explanation:

In the history of USA, Scalawag was a derogatory term used for those white southerners who supported the new government in the process of reconstruction after the American civil War. The Southerner republicans made up the biggest group of delegates. This derogatory term was used by so many historians. So that's why this option is correct.

Carpetbagger was the term used for those who came to Southern States from northern United States after the civil War in America. So as others scab and Lincoln lovers are not relatable with statement.
