The correct analysis of the difference between the roles of mayor and city council members is:
The mayor is the executive, and city council members are legislators.
In this structure, the mayor typically holds the executive role, implementing and enforcing laws and policies, while the city council functions as the legislative body, responsible for creating and passing laws and ordinances. The other descriptions incorrectly assign roles, such as mixing legislative and executive functions or incorrectly categorizing the city council's role.
