Passage: It is generally believed that the outcome of tossing a coin of even quality is random. But in fact, the result of the toss is determined by the momentum and the initial height. Still, making accurate predictions about the outcome of a coin toss is difficult.
Question: Which of the followings explains most the phenomenon stated in the above, that the outcome of the toss is determined by certain factors, but the prediction is difficult?
A. A.For a long time, the toss of a coin has been used as a classic example of random events.
B. B.If a coin of uneven quality is tossed, the outcome can always be accurately predicted.
C. C.If the initial height of the coin toss remains constant, the outcome of the coin toss will only be determined by the toss momentum.
D. D.Accurate prediction of the outcome of a coin toss requires extremely accurate estimates of the initial height and momentum of the coin toss.
