A single-sided DVD has a maximum storage capacity of 4.7GB. This is because it only has one layer of data storage on one side. Option B, 8.5GB, is incorrect because that is the capacity of a dual-layer single-sided DVD, which has two layers of data storage but still on one side. Option C, 9.4GB, is incorrect because that is the capacity of a single-sided DVD with dual-layers on BOTH sides. Option D, 17GB, is incorrect because it is the capacity of a dual-sided DVD, which can store data on both sides of the disc. Therefore, option A, 4.7GB, is the correct and most accurate answer for the storage capacity of a single-sided DVD.
