Listen, I haven't read the book in a while but from general knowledge I would say d. I don't need points or brainliest (always nice) just wanna help. Obviously it cannot be b or c, because glasses represent nothing savage or cruel, furthermore they have no connection to authority within the novel. In fact, there is not authority within the novel, as they boys are trapped stranded alone on an island.
This is why I would say D, because the loss of civilization is a theme throughout the book, and the glasses are a relic of society, when rather than use tools and form modern methods of survival the boys rapidly regress into savagery. D is the only logical answer and fits with the themes of the book
