Option A, Government regulation made goods more costly , is the right answer.

Explanation:

In the United States, the Sherman Antitrust Act of 1890 is antitrust law which regulated competition among enterprises. The Congress of the United States passed this act under the presidency of Benjamin Harrison. The regulation of government in the economic affairs resulted in high prices of goods thus the opponents of the  Sherman Antitrust Act supported the policies of laissez-faire.

it was certainly a debatable decision, mainly because it was based primarily on political - and not on legal or social - views. since the congress at that time was led by members of the republican party, and the territory that the tribes wanted to turn into an exclusively indian state was predominantly democratic, the proposal (as expressed in the constitution) did not succeed, but the constitution itself proved to be of crucial importance in the creation of the state of oklahoma, and, most importantly, it guaranteed the involvement of representatives of the indian tribes in the government of the future joint state.  

as a member of congress, i would have voted to ratify the constitution, or at least to have it tabled. ignoring it was an interested and partial decision.
