Answer:
c. ddr3 d. ddr4
Explanation:
DIMM stands for the dual inline memory module, and it is a kind of computer memory that is in native 64 bits, and that enables a very fast data transfer rate. It happens to be a module that comes with one or various RAM chips that are mounted on a small circuit board through pins that connect then to the motherboard. And at first, we had quad-channel ddr3, but now we have quad-channel DDR4. and hence c. and d. are the correct option.
