Which statement best describes a commission system?

Answer;

A legislative body oversees city departments directly.

Explanation

City commission government is a form of local government in the United States. In a city commission government, voters elect a small commission, typically of five to seven members, on a plurality-at-large voting basis.

Each commissioner serves as the head of one or more departments. In most cities, however, the commission system has given way to the council–manager system. Commission systems are still widely used to govern specific aspects of local government, such as parks, schools, water, and airports.
