The term "service-entrance conductors overhead system" includes which of the following?

The term "service-entrance conductors overhead system" specifically refers to the components involved in delivering electrical service from the utility to the building or structure, primarily concerning the overhead installation of electrical lines. Among the choices, service drops are the segments of overhead conductors that extend from the utility pole or overhead distribution system directly to the service entrance of a building. This makes them a crucial part of the overhead distribution system.

Service cables, while part of the broader electrical distribution, typically refer to the insulated conductors used in a variety of locations including underground or above-ground installations but do not strictly describe the overhead connection to a building. Service subpanels represent a point inside a structure where power is distributed further; however, they do not pertain to the overhead service entrance directly. Utility poles, while supporting the overhead wires, are not classified as conductors themselves. Thus, service drops are the most accurate choice when describing the components of the overhead system defined as "service-entrance conductors."
