Question

Joe tells Pip's convict about the stolen food:

Answer 1

C. Joe shows integrity by allowing the person who needed the food to keep it.

Answer 2

The option is C. Joe is a man of integrity.

When he states  

…”We don't know what you have done, but we wouldn't have you starved to death for it, poor miserable fellow-creature…”

He is feeling that perhaps the convict stole the food for a reason. Obviously he was hungry. The fact that the pie belonged to Mrs Joe, gives certain excuse and allows Joe to diminish the negative effect of the food being stolen, which provides the idea of Joe´s integrity as a human being.
