C Correct answer
Explanation

Floppy disks use magnetic read/write heads that physically contact the disk surface to read and write data, similar to hard drives. CDROM and DVDROM are optical media that use laser beams, not magnetic heads. A read/write head is characteristic of magnetic storage technology.
