Answer:
a. Every year or two, the capacities of computers have approximately doubled without any increase in price.
Step-by-step explanation:
Gordon E. Moore is the co-founder of the organization named Intel Corporation.
He observed that, in every two years, the number of transistors used in the integrated chips installed in the computers are doubled but the cost of the computers are halved or hardly remains the same. His observation is known as Moore's law.
Hence the correct option is (a).
