The given answer, optical drive, is correct because it is one of the options provided and it is a common computer component. An optical drive is a device that uses laser technology to read or write data on optical discs such as CDs, DVDs, or Blu-ray discs. It is used to play or burn media, install software, or access data stored on these discs. The other options, motherboard and mouse, are also computer components, but they are not specifically related to reading or writing optical discs.
