The correct answer is: C. Integrated Circuit
An integrated circuit (IC), also known as a chip, is a small electronic device that contains a number of electronic components, such as transistors, resistors, and capacitors, that are connected together on a single piece of semiconductor material. ICs are used in a wide variety of electronic devices, including computers, cell phones, and automobiles.
A transistor is a semiconductor device that can be used to amplify or switch electronic signals and electrical power. Transistors are used in a wide variety of electronic devices, including computers, cell phones, and televisions.
A resistor is an electrical component that resists the flow of current. Resistors are used in a wide variety of electronic devices, including computers, radios, and televisions.
A semiconductor is a material that has electrical conductivity between that of a conductor and an insulator. Semiconductors are used in a wide variety of electronic devices, including computers, cell phones, and solar cells.
None of the other options are correct.
