A distortion is the alteration of the original shape (or other characteristic) of an object, image, sound, waveform or other form of information or representation. Distortion is usually unwanted. In some fields, distortion is desirable, such as electric guitar (where distortion is often induced purposely with the amplifier or other electronic effect to achieve a unique sound). The slight distortion of analog tapes and vacuum tubes is considered pleasing in certain situations. The addition of noise or other extraneous signals (hum, interference) is not considered to be distortion,[citation needed] though the effects of distortion are sometimes considered noise.
In Geographical Information Systems, portraying the world on a flat map is necessary to appropriately observe the world in a smaller, yet more convenient way. Unfortunately, anytime that a round object is broken up and flattened, it creates many areas of distortion. Some areas stretch, while others are cut. When the earth is projected onto a flat surface there are at least four different types of distortion: distance, direction, angle, and area. It is impossible to preserve all four means of distortion on one flat projection.

So I think the answer is A?
