Solution

The correct option is A Boot sector

Boot sector Viruses are often transmitted by a floppy disk left in the floppy drive.

A boot sector virus is a type of virus that infects the boot sector of floppy disks or the Master Boot Record (MBR) of hard disks (some infect the boot sector of the hard disk instead of the MBR). ... While boot sector viruses infect at a BIOS level, they use DOS commands to spread to other floppy disks.

The boot sector is the first software loaded onto your computer. ... An example of a boot sector virus is Parity Boot. This virus's payload displays the message PARITY CHECK and freezes the operating system, rendering the computer useless.

A boot sector is a region of a hard disk, floppy disk, optical disc, or other data storage device that contains machine code to be loaded into random-access memory (RAM) by a computer system's built-in firmware.
