Answer: D. 2

The correct answer is D. 2.
In computer architecture, there are two fundamental types of RAM:
SRAM (Static RAM): Uses flip-flops to store data. It is very fast and expensive, typically used for CPU Cache. It does not need to be refreshed.
DRAM (Dynamic RAM): Uses capacitors to store data. It is slower and cheaper, used for the Main Memory of a computer. It must be "refreshed" thousands of times per second to keep data from leaking away.
