Step-by-step explanation:
In the novel 'Lord of the Flies,' the fate of the conch and Piggy is closely linked. The correct answer to what happens to the conch and Piggy is D. They are both shattered by the huge boulder. This occurs towards the end of the book when Roger pushes a boulder from a cliff, which hits Piggy and the conch, resulting in both of them being destroyed. This act signifies the end of order and civilization among the boys on the island, as the conch represented authority and structured society, which Piggy had always tried to uphold.
