Which of the following is most consistent with the hypothesis that cliff nesting is adaptive in this goose species?
 A. Many more geese nest on the beaches than on the cliffs.
 B. Cliff-side nesting confers a higher fitness than does beach nesting.
 C. Chicks from cliff nests instinctively step off the cliffs at the appropriate time.
 D. More chicks survive the fall from the cliffs than are killed.
