Read the passage and answer the question. "The first electronic computers of the 1940s filled entire rooms and used thousands of vacuum tubes, which consumed a great deal of power and often failed. The invention of the transistor made computers smaller, faster and more dependable, and the later development of the integrated circuit placed many transistors on a single chip. This steady miniaturisation eventually made the personal computer possible." Which statement is best supported by the passage?
सही उत्तर: ग) The integrated circuit helped make the personal computer possible.
The passage links the integrated circuit to steady miniaturisation, which 'eventually made the personal computer possible'.
