Which of the following options is considered removable media?

Removable media refers to storage devices that can be easily removed from a computer or any other system without the need for the device to be turned off. In this context, a compact disc qualifies as removable media because it can be inserted and removed from a CD drive, allowing for data transfer and storage in a way that does not require a direct connection to a device.

Smartphones and fitness bands are typically considered integrated devices that include their own storage but are not designed primarily as removable media. A laptop, while it often includes removable media options like external drives, is itself not classified as removable media because it is a complete computer system designed for regular use. Therefore, the compact disc stands out as the correct answer because it is fundamentally designed to be easily removable and used as a medium for data storage and transfer.
