B. Sectional tensions would be increased because slavery was prohibited in the new states.
Explanation:
Northwest Ordinance was adopted by the US Congress in 1787 in relation to the so-called Old Northwest or Northwest Territory. In the absence of state unity after independence and the extreme economic and political weakness of the central government, Congress established the republican system throughout the North-West Territory, secured the elimination of feudal relations (prohibited majorate), prohibited slavery and forced labor. Ordonance guaranteed the right to private property. It provided for the formation of three to five new states, and until the finishing the procedure of their establishment, the entire Northwest remained under Congress. The Ordonance was of historical importance, setting a serious precedent for new territories.
