Which of the following, if true, would most help to account for the phenomenon described above? A. The dodo ate a variety of other fruits as well; trees producing these other fruits continued to flourish after the dodo's extinction. B. Although other birds also ate the tree's fruit, the dodo was the largest and thus required the greatest quantities of fruit. C. When the fruit of the tree was not eaten, it gradually decayed, and the seeds within the fruit were deposited in soil. D. The dodo's digestive processes softened the seeds of the tree's fruit before the dodo excreted the seeds; the seeds germinated only after being thus softened. E. The dodo tended to live where the tree's fruit was plentiful; it was in these areas that new fruit trees of that species sprouted before the dodo's extinction.
