The data rate for a DVD at 8x speed is calculated based on the standard data transfer rate of a DVD, which is approximately 1.35 MB/sec at 1x speed. Therefore, at 8x speed, the data rate would be 1.35 MB/sec multiplied by 8, resulting in a total of 10.8 MB/sec.

This calculation shows how DVD speeds are defined and the relationship between the multiple speeds and the base data transfer rate. The choice of 10.8 MB/sec accurately reflects this multiplication of the base rate by the speed factor, confirming it as the correct answer.
