Why each option
Devices that contain high voltage components, even when powered off, such as Switched Mode Power Supplies (SMPS) and older CRT monitors, pose a risk of lethal electric shock.
A Switched Mode Power Supply (SMPS) contains high-voltage capacitors that can retain a lethal electrical charge even after the device is unplugged, posing a serious shock hazard if handled improperly.
A floppy drive operates at low voltages (typically 5V and 12V) and does not contain components that store a lethal electrical charge.
Older Cathode Ray Tube (CRT) monitors contain a high-voltage anode that can store extremely high electrical charges, capable of delivering a lethal shock even hours or days after the monitor has been unplugged.
A keyboard operates at very low voltages (typically 5V supplied by the computer) and poses no risk of lethal electric shock.
