Step-by-step explanation:
The correct answer is b] live.
A Linux distribution that is running directly from a removable disk, without being installed on the hard drive, is known as a live distro. It allows you to boot and use the operating system without making any changes to your computer's hard drive. This is useful for testing or trying out different Linux distributions without committing to a permanent installation.
With a live distro, you can simply insert the removable disk (such as a USB flash drive) into your computer, choose to boot from it, and the operating system will load up and run from the disk.
