The north’s rapid economic growth during the civil war was stimulated by a. the elimination of taxes on defense industries b. a reduction in the number of immigrants c. increased government demand for many products d. enslaved persons filling industrial jobs

The North's rapid economic growth during the Civil War was stimulated by C. increased government demand for many products. Since the war was ongoing, America needed many products, such as war supplies, medical supplies, food, clothes, etc. During wartime, government seeks more and more products so it can go through with the war.Hope I helped! :) Cheers!
