Which of the following is an optical storage disc?

Explanation:
Optical storage uses light to read data from a disc. A DVD fits this category because it stores data as tiny pits and lands that a laser reads. The USB flash drive and the solid-state drive rely on flash memory (electronic storage with no moving parts), while the hard drive uses magnetic storage on spinning disks. Since only the DVD uses light-based reading to access data, it is the optical storage disc.
