Answer: B
Data is cached to reduce average access time.
Cache memory is a small, very fast memory placed between the CPU and main memory. It keeps copies of the data and instructions used most often or most recently, so that the processor can get them quickly instead of waiting for the slower RAM. This lowers the average time taken to access memory.
A cache does not save storage space; it adds another copy. It does not keep irrelevant data, since the point is to keep data likely to be needed again. And it is temporary, volatile memory, not a permanent archive.
