Answer: Choirboys
Step-by-step explanation:
When they were on the beach and Ralph saw a conch, Piggy told him that they can use the conch as a trumpet and blow it so that others can Kno their whereabouts and others survivors can come to the beach.
The conch was blown and boys of about 6 to 12 years came to the beach towards Ralph. The last to get to the beach were Jack and the choirboys. They were dressed in their black caps and their long black cloaks.
