A. B. C. D.C.
To fix the issue with a Bluetooth mouse not working properly on a Linux system, the systems administrator should use the command "C. modprobe "r bluetooth".
Here is an explanation of each command and why "modprobe -r bluetooth" is the correct choice:
A. lsmod "i bluetooth: This command lists the currently loaded kernel modules and searches for the module "bluetooth" in the list. The "-i" option is not a valid option for the lsmod command, so this command will fail with an error.
B. insmod bluetooth: This command inserts the "bluetooth" module directly into the Linux kernel, which is not the correct approach for fixing issues with a Bluetooth mouse. This command is more appropriate for manually adding a new kernel module that is not already loaded.
C. modprobe "r bluetooth: This command removes the "bluetooth" module from the Linux kernel. This can help fix issues with a Bluetooth mouse by forcing the system to reload the module and reinitialize the Bluetooth stack.
D. depmod "i bluetooth: This command updates the module dependency database for the "bluetooth" module, but does not directly address any issues with a Bluetooth mouse. This command is useful for resolving issues with module dependencies, but it is not the appropriate command for fixing issues with a Bluetooth mouse.
Therefore, the correct command to fix the issue with a Bluetooth mouse not working properly on a Linux system is "modprobe -r bluetooth".
