Solution

The answer is the second one (B): DDR3-2000.

Explanation for each option:

A. DDR3-1600: This is incorrect because DDR3-1600 refers to a memory module with a data transfer rate of 1600 MT/s (megatransfers per second). The PC3-16000 designation indicates a higher data transfer rate.

B. DDR3-2000: This is correct. PC3-16000 refers to DDR3 memory with a data transfer rate of 2000 MT/s. The "PC3" designation is used for DDR3 memory, and the "16000" refers to the theoretical maximum bandwidth in MB/s (megabytes per second), which is calculated as 2000 MT/s * 8 bytes per transfer = 16000 MB/s.

C. DDR-2000: This is incorrect because DDR-2000 would refer to an older type of DDR memory, not DDR3. The "PC3" designation specifically refers to DDR3 memory.

D. PC3-2000: This is incorrect because PC3-2000 would refer to DDR3 memory with a data transfer rate of 2000 MB/s, which is much lower than the 16000 MB/s indicated by PC3-16000.

Summary: The appropriate memory chips you would find on a stick of PC3-16000 are DDR3-2000.
