Show answer & explanation
Correct answer: A
Concept
To arrange storage devices by increasing capacity, compare their standard nominal capacities in a common unit.
After converting MB, GB, and TB to the same scale, place each device class from the smaller usual capacity to the larger usual capacity.
Application
A CD-ROM commonly stores about 650–700 MB.
A single-layer DVD commonly stores 4.7 GB.
A single-layer Blu-ray Disc commonly stores 25 GB.
Hard disks are commonly available in capacities of hundreds of GB or several TB.
Thus, the increasing-capacity order is CD-ROM → DVD → Blu-ray Disc → Hard Disk.
Cross-check
Using decimal approximations, 700 MB < 4,700 MB < 25,000 MB < 100,000 MB or more, which confirms the same order.
