Answer:
A. True.
Step-by-step explanation:
E-mail is an acronym for electronic mail and it can be defined as an exchange or transmission of computer-based data (messages) from one user to another over a communications network system.
Also, a distributed application refers to a software program that is capable of running on several computer systems and can communicate effectively through a network.
E-mail is the most common distributed application that is widely used across all architectures and vendor platforms because it primarily operates on a client-server model, by providing users with the requested services through the Simple Mail Transfer Protocol (SMTP) using the standard port number of 25.
