A DVD (Digital Versatile Disc) is an optical disc used to store digital data such as videos, software, music, and documents. It uses laser technology to read and write data on its surface, making Option B (Optical disc) the correct answer.
Optical discs store information in the form of tiny pits and lands on a reflective surface. A DVD drive uses a laser beam to read this information and convert it into digital data that the computer can process. DVDs can store much more data than CDs, with a standard single-layer DVD holding 4.7 GB of data and a dual-layer DVD storing up to 8.5 GB.
