Final answer:
In 'Lord of the Flies,' Piggy is not held as a prisoner by Jack and his hunters; this cruelty is experienced by other characters like Eric and Wilfred.
Step-by-step explanation:
The character from 'Lord of the Flies' who is not held as a prisoner by Jack and his hunters is D. Piggy. Eric, one of the twins, is indeed captured by Jack's tribe, alongside his brother Sam. Wilfred is another character who is mentioned to have been punished by Jack for reasons that are not entirely clear within the narrative. However, Piggy, despite facing various forms of brutality and ultimately meeting a grim fate, is not depicted as being captured or held prisoner by Jack and his hunters in the same manner as some of the others are.
