Which of the following represents an optical data disk?

Explanation:
Optical data disks store information on a surface with pits and lands and are read by a laser in an optical drive. The CD-ROM fits this description as a classic optical disc designed specifically for storing data to be read optically. The other items aren’t discs that use optical reading: RAM is volatile memory used for quick data access by the CPU, the CPU is the processor itself, and ROM is non-volatile memory embedded in hardware, not a disc. So the CD-ROM is the one that represents an optical data disk.
