Answer: c. it failed to take advantage of opportunities presented by Moore's Law.
Explanation:
Moore's law is states that the number of transistors in a dense integrated circuit doubles roughly every two years.
The observation got its name after Gordon Moore, the co-founder of Fairchild Semiconductor and CEO of Intel, whose paper in 1965 showed a pattern of doubling every year in the number of transistors per integrated circuit, and he predicted that this rate of growth would continue for at least another decade.
In 1975, he reviewed the forecast to doubling every two years, at a compound annual growth rate of 41.4percent.
