The correct answer, is b. Becoming greedy, and reaching for too much, can result in losing everything.
Indeed, Pahom becomes too greedy to understand that he already had a very comfortable situation and that he did not need that much land. Because he overreaches for as much land as he can physically cover as he runs, he dies of exhaustion, losing all the good things he already have, including his own life.
The answer is death or exile. Something is ruining the crops in Thebes, illness is killing the livestock and women in labor are having trouble during childbirth. Therefore, the solution is to escape the land.
