Final answer:
A common carrier and an electronic publisher have different roles. Common carriers transmit information without control over content, while electronic publishers have control over the content they distribute.
Step-by-step explanation:
A common carrier and an electronic publisher are two different entities that have distinct roles. A common carrier refers to a company or organization that provides public telecommunications services, such as telephone or internet access, to the general public. They are responsible for transmitting information without any control or censorship over the content. On the other hand, an electronic publisher is an entity that distributes and makes available digital content, such as e-books, articles, or online magazines. They have the ability to control and review the content before publishing it.
So, the correct option in this case would be A) A common carrier may examine content before distributing it; an electronic publisher may not.
