Answer is Right!
Answer is Wrong!
The odd one out is telegram.
Electricity, telephone, and post are all forms of communication. Telegram is a form of communication that is no longer in use. It was a way to send a message over a long distance using a telegraph machine. The telegraph machine used electrical signals to send the message. The message was then printed out on a piece of paper at the other end.
Telegrams were once a popular way to communicate, but they have been replaced by other forms of communication, such as email and text messaging. Telegrams are no longer available in many countries.
Here is a brief explanation of each option:
- Electricity is a form of energy that is used to power devices and machines. It is produced by generators that convert mechanical energy into electrical energy. Electricity is used in homes, businesses, and industries.
- Telephone is a device that allows people to communicate with each other over long distances. It uses electrical signals to transmit sound. Telephones are used for personal and business purposes.
- Post is a system for delivering mail. It includes the collection, transportation, and delivery of letters, parcels, and other items. The post is used to send mail to people and businesses all over the world.
