The correct answer is C. 1000 volts.
A static jolt of as little as 1000 volts can fry most any PC integrated circuit. This is because integrated circuits are very sensitive to static electricity. When a static charge builds up on a person’s body, it can discharge when they touch a grounded object, such as a computer. This discharge can cause a large amount of current to flow through the integrated circuit, which can damage or destroy it.
To prevent static damage to your computer, you should take steps to discharge any static electricity on your body before touching it. You can do this by touching a grounded object, such as a doorknob, before you touch your computer. You can also use an anti-static wrist strap to ground yourself.
If you think your computer may have been damaged by static electricity, you should take it to a qualified technician for diagnosis and repair.
