Answer:
A) Starbuck is practical; Ahab is obsessed.
Step-by-step explanation:
This is the main difference between the two men. Ahab is obsessed with chasing the whale. He believes this to be his mission, and he is willing to endanger the entire crew. On the other hand, Starbuck is a lot more reasonable. He believes that the mission is foolish and dangerous, and that Ahab has gone mad. He is the voice of reason and practicality that contrasts with Ahab's passion and intensity.
