The correct options are b. has fished and c. has been fishing.
Explanation:
The sentence implies an action that started in the past and continues or has relevance to the present. "Has fished" is a Present Perfect Simple, indicating completed actions in the past with present relevance. "Has been fishing" is a Present Perfect Continuous, indicating an action that started in the past and continues up to the present. Since the question requires two correct options, both fit well in this context.
