Answer: B. He thinks the request shows Yun Ok's foolishness.
The hermit thinks the request shows Yun Ok's foolishness because her husband's condition is not like a disease or illness which can be cured by a potion or medicine. The truth is, she doesn't need any potions, amulets, drinks, or medicines just to bring back her husband to his old self again. The hermit wants to show to Yun Ok that she only need tolerant and gentle care to change her husband.
