The correct answer is D. Unplug the PC and remove phone line from the modem.
A lightning rod is not a guarantee that your PC will be protected from a lightning strike. In fact, it is possible for a lightning strike to travel through the ground and into your home through the phone line or power cord. To protect your PC, you should unplug it from the power outlet and remove the phone line from the modem.
Option A is incorrect because a lightning rod does not guarantee that your PC will be protected from a lightning strike.
Option B is incorrect because a surge protector is not a guarantee that your PC will be protected from a lightning strike.
Option C is incorrect because a surge protector on your PC and phone line to your modem is not a guarantee that your PC will be protected from a lightning strike.
Option E is incorrect because standing on your PC will not protect it from a lightning strike.
