When troubleshooting a blank monitor, you should first ensure that the power and video cables are properly plugged in at both ends. Next you would check the monitor's settings, and as a last resort, swap out the monitor with a known working one.

Correct Option(s):

c) Check the monitor's power and video cables.

Incorrect Option(s):

a) Replace the monitor. - Replacing the monitor would be one of the last actions you would try. This should only be done after you have tried all other, simpler, troubleshooting options. If you replace the monitor and there is still no picture, you may have a video card problem and would need to move on to troubleshooting that device.
b) Replace the video card. - This would be done only after you have tried all of the troubleshooting steps for the monitor, and have determined that the video card is faulty.
d) Reinstall the operating system. - This would be the least likely solution to this problem. A monitor problem may be caused by an improperly installed or outdated driver, but reinstalling the operating system would not fix this.
