B1, 3, 4, 2

C2, 4, 3, 1

D3, 1, 2, 4

Correct answer: (A) 3, 1, 4, 2

Explanation

In increasing capacity a CD-ROM is smallest, holding about 700 megabytes, which is number 3.

A DVD comes next at roughly 4.7 gigabytes, which is number 1.

A Blu-Ray Disk follows with 25 gigabytes or more, which is number 4.

A hard disk is largest, commonly reaching hundreds of gigabytes or terabytes, which is number 2.

This gives the ascending order 3, 1, 4, 2.

Optical discs pack more data as their laser wavelength shortens from CD to DVD to Blu-Ray.
