Solution

The correct option is A CR-R disks

CR-R disks media have the ability to have data/information stored (written) on them by users more than once.

CD-R (for compact disc, recordable) is a type of write once, read many (WORM) compact disc (CD) format that allows one-time recording on a disc. The CD-R (as well as the CD-RW) format was introduced by Philips and Sony in their 1988 specification document, the Orange Book. Short for Compact Disc-Read Only Memory, a CD-ROM (shown right) is an optical disc which contains audio or software data whose memory is read only. A CD-ROM Drive or optical drive is the device used to read them.

A standard CD-R is a 1.2 mm (0.047 in) thick disc made of polycarbonate about 120 mm (4.7 in) or 80 mm (3.150 in) diameter. The 120 mm disc has a storage capacity of 74 minutes of audio or 650 Megabytes of data.
