An integrated circuit is

  • A.A complicated circuit
  • B.An integrating device
  • C.Much costlier than a single transistor
  • D.Fabricated on a tiny silicon chip

Answer: D

Correct answer: Fabricated on a tiny silicon chip

An integrated circuit is a complete circuit - transistors, resistors and the connections between them - fabricated together on one small piece of silicon. Making them all at once, by the same photolithographic process, is what makes the IC dramatically cheaper than the equivalent discrete components, not costlier.
