D: shay's rebellion

C: whiskey rebellion

Explanation:

The whiskey rebellion was a movement in the frontier of the United States at the time, especially in Western Pennsylvania, that lasted from 1791 to 1794.

The rebellion emerged because Washingont's secreatry of treasury, Alexander Hamilton, imposed a tax on domestic whiskey, in order to raise government revenue.

This tax enraged frontier people who thought it was discriminatory.

The rebellion collapsed after a relatively peaceful intervention by the state militia, commanded by Washington himself.
