The correct answers would be option A: "There are plenty of giraffes and wild asses on the islands", option B: "The wild boars on the island are as big as buffaloes, with 14 lb tusks", and option C: "The gryphon birds are monstrous in size". All these details show that the author is captivated by the islands because he saw things that he had never seen before, these being the quantity of wild animals or their size and huge atributes.
Option D is not a relevant detail since it shows no wonder and option E is just an informative detail used as support, not as a remarkable thing by itself.
