Final answer:
An administrative body is most likely to conduct hearings on licensing and zoning applications, which are key aspects of zoning regulations and municipal governance.
Step-by-step explanation:
The function most likely to be carried out by an administrative body is hearing licensing and zoning applications. Administrative bodies, such as boards of zoning appeals, are often created by statutes to address matters pertaining to the use of land and structures within a certain jurisdiction. These boards have a quasi-judicial function, conducting hearings with sworn testimony by witnesses, and their decisions are subject to court review. These processes are essential to enforce zoning regulations which are designed to divide a municipality into residential, commercial, and industrial zones, imposing detailed restrictions within each.
