Which of the following quotations most clearly shows Piggy's dismay at learning that there are no adults on the island?
"'All them other kids,' the fat boy went on. 'Some of them must have gone out. They must have, mustn't they?' The fair boy began to pick his way as casually as possible toward the water. He tried to be offhand and not too obviously uninterested, but the fat boy hurried after him."
"'Where's the man with the megaphone?' The fair boy shook his head. 'This is an island...Perhaps there aren't any grownups anywhere.' The fat boy looked startled. 'There was that pilot. But he wasn't in the passenger cabin, he was up front.'"
"'Aren't there any grownups at all?' 'I don't think so.' The fair boy said this solemnly; but then the delight of a realized ambition overcame him. In the middle of the scar he stood on his head and grinned at the reversed fat boy. 'No grownups!'"
"'I expect there's a lot more of us scattered about. You haven't seen any others, have you?' Ralph shook his head and increased his speed. Then he tripped over a branch and came down with a crash. The fat boy stood by him, breathing hard."
"Piggy flushed suddenly. 'My dad's dead,' he said quickly, 'and my mum -' He took off his glasses and looked vainly for something with which to clean them."
