Answer:

Option d power cords to the motherboard are not connected

Explanation:

A motherboard is a hardware attached to many components inside the computer such as central processing unit (CPU), memories and peripherals. If the power cords to the motherboard are not connected, there is no way the computer can start and boot the operating system even though the power supply is turned on.

The rest of the options are not true as the computer will still be turned on even if one of those cases happens in reality.
