• B. 8.5GB
• C. 25GB
• D. 50GB

Answer: (A)

A single-layer digital versatile disc (DVD) has a storage capacity of approximately 4.7GB. This capacity is specifically for the standard DVD format, which is designed to hold video, data, and other types of digital content. The amount allows for the storage of a full-length movie or several hours of video, making it a popular choice for both commercial and personal use. In the context of other storage capacities, 8.5GB refers to dual-layer DVDs, which can store more information by using two layers on the same disc. Options like 25GB and 50GB pertain to Blu-ray discs, which have significantly larger storage capacities due to different manufacturing techniques and technologies, enabling high-definition content. Understanding these specifications helps distinguish between the various types of optical discs available and their suitable applications.
