The earliest known records of wartime activities detail the history of the use of carrier pigeons to communicate classified military information. Many people are not aware that the birds were also used extensively in the world wars of the twentieth century. Even today, their uncanny ability to fly home over great distances makes them valuable even to modern military units that need a way to deliver messages without the use of portable electronic devices whose signals can be intercepted.

The statements above, if true, best support which of the following conclusions?

A. The use of carrier pigeons is usually preferable to the use of portable electronic devices when a military unit needs a way to send classified military information.
B. The messages that carrier pigeons carry cannot be intercepted.
C. The use of carrier pigeons decreased once portable electronic devices became practical in warfare.
D. Carrier pigeons were used in warfare prior to the date of the earliest known record of wartime activity.
E. Carrier pigeons are still used extensively by modern military units.
