The correct answer to the given question is:

D) None of above

Explanation:

Compact Disc Read Only Memory (CD-ROM) is a modification of a compact disc designed to store computer data in text and graphic form, as well as high-quality stereo sound. The original data format standard was defined by Philips and Sony in the 1983 Yellow Book.

As with other CD adaptations, CD-ROM data is encoded as spiral tracks starting at the center and ending at the farthest edge of the disc. The spiral track contains about 650 MB of data. About 5.5 billion bits. The distance between two rows of feet, measured from the center of one track to the center of the next, is called the track pitch. The track pitch is 1.5 to 1.7 µm, but in most cases, it is 1.6 µm.
