Integrated Circuits (IC) chips used in computers are made with

Gold
Silver
Silicon
Copper E. None of these

The correct answer is C. Silicon.

Integrated circuits (ICs) are made from a thin layer of silicon, which is a semiconductor. Semiconductors are materials that can conduct electricity under certain conditions. Silicon is a good choice for ICs because it is abundant, relatively inexpensive, and has good electrical properties.

Gold, silver, and copper are all metals that are also good conductors of electricity. However, they are more expensive than silicon and are not as well-suited for use in ICs.

E is not a correct answer because it does not specify a material.
