What is the capacity of a Dual-Layer Blu-Ray disc?

  1. 25GB

  2. 50GB

  3. 650MB

  4. 700MB

The correct answer is: 50GB

A Dual-Layer Blu-Ray disc has a capacity of 50GB, making it the largest storage capacity among the given options. Option A, 25GB, is the capacity of a Single-Layer Blu-Ray disc, which is half of the capacity of a Dual-Layer disc. Option C, 650MB, is the capacity of a CD-ROM, which is significantly smaller than a Blu-Ray disc. Option D, 700MB, is the capacity of a standard DVD, which is also smaller than a Blu-Ray disc. Therefore, the correct answer is B because the capacity of a Dual-Layer Blu-Ray disc is 50GB.
