What speed does a 4x CD data rate achieve?

150 KB/sec
300 KB/sec
600 KB/sec
1200 KB/sec

The correct answer is: 600 KB/sec

A 4x CD data rate achieves a speed of 600 KB/sec. This is because "4x" refers to the maximum speed at which data is read from a CD, and "600 KB/sec" is the corresponding data transfer rate. Option A, 150 KB/sec, is too slow to be considered 4x. Option B, 300 KB/sec, is half of 4x. Option D, 1200 KB/sec, is twice the speed of 4x. Therefore, Option C is the correct answer.
