The correct answer is (d), optical disc.
An optical disc is a data storage medium that uses laser technology to read and write data. The most common type of optical disc is the compact disc (CD), which is used to store music and data. Other types of optical discs include the digital versatile disc (DVD), which is used to store high-definition video and data, and the Blu-ray disc, which is used to store high-definition video and data with even greater capacity than DVDs.
Magnetic discs and magnetic tape are both storage media that use magnetic fields to store data. Magnetic discs are typically used to store data in personal computers and other electronic devices, while magnetic tape is typically used to store data in large computer systems.
Punched cards are a type of data storage medium that uses holes punched in a card to represent data. Punched cards were once widely used in computers, but they have been largely replaced by other types of storage media, such as magnetic discs and optical discs.
