Answer:
The correct answer is A.
Explanation:
Moore's Law states/predicts that the maximum number of transistors that can be used on integrated circuits (processors etc.) will be doubled every two years so it basically predicts an exponential growth in terms of transistors used.
Doubling the number of transistors used means that it will almost certainly increase the performance of the processors. Of course there are a lot of other variables that the performance depends on but Moore's Law is proven to be true and is being used since 1960's. The answer given in option A is the one that best reflects on this law.
I hope this answer helps.
