What does Moore's Law primarily discuss?

Moore's Law primarily addresses the observation that the number of transistors that can be placed inexpensively on an integrated circuit doubles approximately every two years. This exponential increase in transistor density tends to result in greater computational power and efficiency while also contributing to a reduction in relative cost per transistor. As the technological capability improves, it impacts various aspects of technology, including performance and miniaturization of electronic devices.

This principle has significant implications for the growth and progression of technology, influencing everything from computer processors to smartphones and beyond. The doubling of transistors allows for advancements in speed and functionality, which is why option C accurately captures the essence of Moore's Law.
