Answer:
Hi!
The correct answer is the a.
Explanation:
The Moore's law is an a empirical law that Gordon Moore predicted doing some observations about how the density of the transistors on a integrated circuit was increasing over time.
For example, this law state that if you have an integrated circuit with: 1000 transistors in 1980 then in 1981 and six months later you will have the same integrated circuit with 2000 transistors, and so on..
- Jan 1980: 1000 transistors.
- Jul 1981: 2000 transistors.
- Jan 1983: 4000 transistors.
- Jul 1984: 8000 transistors.
And that's the reason because its cost will fall too.
I don't know if it's possible, but try using landscape. It may fit
