How much data can a BluRay disc hold?

  1. 9.4GB

  2. 25GB

  3. 50GB

  4. 128GB

The correct answer is: 25GB

A BluRay disc can hold up to 25GB of data. This is significantly more than the 9.4GB capacity of a standard DVD, as well as the 50GB capacity of a dual-layer DVD. The option of 128GB is incorrect because it is not currently possible for a BluRay disc to hold that much data. While there are BluRay discs with larger storage capacities in development, they are not yet widely available for consumer use. Therefore, the best answer is B.
