What is the data rate of a standard BluRay?

4.5 MB/sec
36 MB/sec
512 Bytes
54MB/sec

The correct answer is: 4.5 MB/sec

A BluRay disc has a maximum data rate of 36 MB/sec, but the standard rate for most BluRay discs is 4.5 MB/sec. This is due to the fact that BluRay discs have a large capacity of 25GB per layer, so a slower data rate is necessary to ensure that the entire disc can be read without skipping or errors. Options B, C, and D are incorrect because they all have data rates that are either too high or too low for a standard BluRay disc. While option D is close to the maximum data rate for a BluRay disc, it is still incorrect as it is higher than the standard data rate. Option C, with a data rate of 512 Bytes, is significantly lower than the standard data rate and is not a viable option. Option B, with a data rate of 36 MB/sec, is too high and is only the maximum data rate for a BluRay disc, not the standard. Therefore, the correct answer is A, 4.5 MB/sec.
