Which of the statements given below are correct?

An Integrated Circuit (IC) is a collection of several circuits (transistors) packed on a single chip. The invention of ICs in the history of computing led to:
(A) increased reliability of computers.
(B) reduced cost of computers (because they could be mass manufactured),
(C) reduced size of computers.
Choose the correct answer from the options given below:

Correct option is D

All three statements are correct:
(A): The invention of Integrated Circuits (ICs) increased the reliability of computers because fewer components meant fewer points of failure.
(B): ICs reduced the cost of computers by enabling mass production of complex circuits on a single chip.
(C): ICs drastically reduced the size of computers by consolidating multiple components into a single chip.
Information Booster:
1. ICs allowed computers to become smaller, more reliable, and more affordable, leading to widespread adoption.
2. Early computers used vacuum tubes, which were much larger and less reliable than transistors found in ICs.
