What amount of data can a DVD typically store?

A standard single-layer DVD can store approximately 4.7 GB of data, while a dual-layer DVD can hold about 8.5 GB. This makes the range of 4-8.4 GB the most accurate choice for typical DVD storage capacity. The amount of data storage on DVDs is primarily due to their structure, which utilizes a laser to read and write data on a reflective surface.

When considering options beyond this range, such as 1-2 GB or 12-16 GB, they do not reflect the actual storage capacity of standard DVDs. The 25 GB option pertains to Blu-ray discs, which have a significantly larger storage capacity due to their different technology and design. Thus, the choice of 4-8.4 GB aligns with common knowledge regarding DVD storage capabilities.
