Final answer:

Step-by-step explanation:
The outcome of the Whiskey Rebellion was significant in that it showed that the new national government had the power necessary to force compliance with their laws. In response to the rebellion, President Washington created a thirteen-thousand-man militia to put down the rebellion, demonstrating the government's ability to enforce its authority.
This event also strengthened the power of the national government. The Federalists, who were in power at the time, saw the rebellion as a test of the government's strength and believed that crushing it decisively would show European monarchies that a republican form of government could enforce laws and protect liberty and property.
Therefore, the correct answer is A) Have the power necessary to force compliance with their laws.
