Identify the correct order as per increasing data storage capacity :

  • A.CDROM, DVD, Cartridge, BlueRay Disc
  • B.DVD, Cartridge, BlueRay Disc, CDROM
  • C.Cartridge, CDROM, DVD, BlueRay Disc
  • D.BlueRay Disc, DVD, Cartridge, CDROM

Answer: C

The order of increasing data storage capacity in the key is cartridge, CD-ROM, DVD and Blu-ray disc, so the answer is C.

A CD-ROM holds about 650 to 700 MB, a single-layer DVD about 4.7 GB and a Blu-ray disc 25 GB or more. The key puts the cartridge, a tape or disk cartridge of small capacity, first.

The other orders place the Blu-ray disc, which has the largest capacity of the four, before the others or put the CD-ROM after the DVD, which cannot be right.
