How fast is an 8x CD data rate?

600 KB/sec
900 KB/sec
1200 KB/sec
1.35 MB/sec

The correct answer is: 1200 KB/sec

An 8x CD data rate refers to the speed at which data is transferred from a CD to a computer. This speed is measured in multiples of the original CD transfer rate, which is 150 KB/sec. Therefore, 8x CD data rate would be 8 times the original rate, which is 1200 KB/sec. Option A, B, and D are incorrect as they are not in line with the original rate or the multiplier of 8.
