Final answer:
Amateur radio service is not a common carrier because it is not regulated under such a category but used for personal or public service without operating as a business. Common carriers like telegraph, telephone, and cell phone services are provided to the public at large under government regulation.
Step-by-step explanation:
which of the following would not be considered a common carrier is: e) amateur radio service. A common carrier provides services to the general public under license or authority provided by a regulatory body and must do so without discrimination. Examples of common carriers include telegraph, telephone, and cell phone service providers because they offer their services to the public at large under government regulation. In contrast, amateur (or ham) radio operators, typically use the radio spectrum for personal enjoyment or public service, and do not operate as a business or for profit, and are not regulated as common carriers.
Services like police protection, roads, and primary education are considered nonexcludable because they are available to all members of the public without direct charges, and individuals cannot be effectively excluded from using them. These services are typically provided by the government because they are public goods that the market may not provide efficiently due to their nonexcludable and nonfrivolous nature.
