The correct option is "telegram".
A telegram is a message that is sent by cable from one place to another. It is a form of communication that was widely used in the past, before the advent of modern electronic communication systems like email, text messaging, and social media.
To send a telegram, the sender would go to a telegraph office and dictate the message to a telegraph operator, who would transmit it over the telegraph network to the receiving station. The message would be recorded on a strip of paper using a telegraph key, which converts the sender's message into a series of electrical pulses that are transmitted over the wire.
At the receiving station, the message would be printed out on a piece of paper by a telegraph printer. The paper strip with the recorded message would then be delivered to the recipient.
Telegrams were often used to convey urgent or important messages, such as news of births, deaths, or emergencies, as well as business or government communications. The cost of sending a telegram was based on the number of words in the message, so senders had to be concise and clear in their communication.
In summary, a telegram is a printed message that is sent by cable from one location to another. It was a popular form of communication in the past and was used for urgent or important messages.
