10. Which of the following best describes the role of pits and lands in storing a bit value on a manufactured CD or DVD

A. Laser light is reflected poorly from a land because it is dyed a darker color than a pit. The difference in the strength of the reflected laser light is interpreted as a zero or one value.

B. Laser light reflected from a pit scatters. Laser light reflected from a land is reflected strongly. The difference in the strength of the reflected laser light is interpreted as a zero or one value.

C. Laser light is reflected poorly from a pit because it is dyed a darker color than a land. The difference in the strength of the reflected laser light is interpreted as a zero or one value.

D. Laser light reflected from a land scatters. Laser light reflected from a pit is reflected strongly. The difference in the strength of the reflected laser light is interpreted as a zero or one value.
