What bus speed does PC-2100 RAM support?

100MHz
133MHz
200MHz
266MHz

The correct answer is: 133MHz

PC-2100 RAM supports a bus speed of 133MHz. This means that it can transfer data at a rate of 133 million cycles per second. Other options, such as 100MHz, 200MHz, and 266MHz, do not match the specific bus speed of PC-2100 RAM and would not be compatible. Therefore, B is the correct answer as it aligns with the supported bus speed for this type of RAM.
