B.Setting a sales tax on all goods sold in the city
Explanation:
There are several things that a local level government can do, and the closest one in the options is Setting a sales tax on all goods sold in the city, this is because every local government has the ability to tax things, at some point for example New York has a tax on any modified bagel, if it is sold uncut, it´s tax free but as soon as you cut it or add cream to it it has a tax of 8 cents. The other options are things that cannot be totally decided on a local level, for example the zoning laws should be seen in a state level, and borders and appointing justices should be seen in a federal level.
