Which was the first Southern state to approve the Fourteenth Amendment and be readmitted to the Union?

Virginia

Tennessee

South Carolina

Georgia

I believe it was Georgia though I could be Mistaken

Tennessee, it was last state to leave the Union and first to join, largely due to part that East Tennessee was Union sympathizer, little no farming land in the region, and east Tennessee actually tried to leave the confederacy and go back to the union but was denied by Jefferson Davis.
