C)hard drive.
D)USB port.

Question

Quizplus · Accepted Answer

Cache is a type of memory that is located closest to the CPU, making it the quickest option for storing and retrieving frequently used data. CPUs will often access data from cache in order to speed up processing times.

Answer: C and D 
 Neither CMOS nor USB ports are typically used for storing the type of data that CPUs need to access quickly for processing. Hard drives can be used for storing such data, but they are much slower to access than cache. Thus, while hard drives may eventually be used for retrieving data, CPUs will typically first look to cache for any frequently accessed data, such as instructions or bits of code.
