Which of the following best describes a common carrier?

A common carrier is defined as a transportation service that is available to the general public for the movement of goods or passengers for a fee. This type of carrier must adhere to certain regulations and legal obligations, providing their services without discrimination to any customer willing to pay the agreed-upon rate. Common carriers typically operate with a license and are responsible for transporting goods safely and efficiently.

The focus on the general public is crucial because it distinguishes common carriers from private carriers, which work on a contract basis with specific clients. By serving a broad clientele, common carriers play a vital role in the logistics and transportation industries, contributing to a competitive marketplace where multiple options are available for consumers.

In contrast, other options describe carriers that either serve restricted clientele, operate only under specialized conditions, or are limited to specific governmental contracts, which does not align with the definition of a common carrier. Therefore, the description that emphasizes the service to the general public is the most accurate understanding of what a common carrier encompasses.
