Final answer:
In 'Lord of the Flies,' Roger is not held as a prisoner by Jack and his hunters; he is one of Jack's loyal followers.
Step-by-step explanation:
The character from William Golding's novel Lord of the Flies who is not held as a prisoner by Jack and his hunters is c) Roger.
In the novel, Samneric (a) are taken captive and made to join Jack's tribe, Simon (b) encounters the hunters but is tragically killed before ever being held prisoner, and Piggy (d) remains with Ralph and is never captured by Jack's group. Roger, on the other hand, is one of Jack's followers and plays the role of a torturer rather than being a prisoner.
