    Encryption is the process of encoding messages or information so that only authorised parties can read it.
    All messaging services like WhatsApp, Viber, Google Chat, Yahoo messenger use encrypted services. Banks (payment gateways) and e-commerce sites also use encryption to protect financial and private data, including passwords.
    Encryption is also used to protect data in transit, such as data being transferred via networks (e.g. the Internet, e-commerce), mobile telephones, wireless microphones, wireless intercom systems, and Bluetooth devices and bank automatic teller machines.

    Answer:

    Encryption is a technique that is used to secure data transmission by converting plain text into cipher text. This ensures that the data is transmitted securely by making it unreadable to unauthorized entities. The following services generally use encryption to secure data transmission:

    1. Payment Gateways: Payment gateways are online services that enable businesses to accept payments from customers. These services use encryption to ensure that the payment information is transmitted securely between the customer's browser and the payment gateway's server.

    2. Messaging Services: Messaging services such as WhatsApp, Telegram, and Signal use end-to-end encryption to secure the messages that are transmitted between users. This ensures that only the intended recipient can read the messages.

    3. Wireless Microphones and Bluetooth Devices: Wireless microphones and Bluetooth devices use encryption to ensure that the audio signals transmitted between devices are secure and cannot be intercepted by unauthorized entities.

    4. Bank Automatic Teller Machines: ATMs use encryption to ensure that the data transmitted between the ATM and the bank's server is secure. This includes PIN numbers and account information.

    Therefore, option D, which includes all of the above services, is the correct answer.
