In QEMU/KVM, the legacy parameter -hdb file.img attaches a disk image as theprimary IDE slave device.
According to QEMU documentation, this corresponds to an IDE device withindex 1, media typedisk, and interfaceIDE.
The modern equivalent using the -drive syntax is:
-drive file=file.img,index=1,media=disk,if=ide
OptionDmatches this mapping precisely. The other options use invalid or unsupported parameter combinations and do not correctly represent the IDE device mapping.
Therefore, the correct answer isD.
