Crossbill Finches Have Beaks That Overlap with the Top Beak

Crossbill finches have beaks that overlap with the top beak to one side or the other of the lower beak. Most populations have 50:50 ratios of "right-handed" and "left-handed" beaks, and the handedness of the beaks is thought to be randomly determined, so we expect to see equal numbers of right-beak and left-beak finches. Consider a survey of 140 crossbill finches, which reveals 84 with right beaks and 56 with left beaks. What is the conclusion of a two-sided binomial test using the normal distribution to approximate the binomial?

A) Fail to reject null hypothesis, we lack evidence that the handedness of the beaks is non-random.
B) Fail to reject null hypothesis, we have evidence that the handedness of the beaks is non-random.
C) Reject null hypothesis, we lack evidence that the handedness of the beaks is non-random.
D) Reject null hypothesis, we have evidence that the handedness of the beaks is non-random.
