Which best describes the manager

I'm not sure what choices you have but I can make a general comment. Marlow's direct supervisor, he is a hard, greedy man who values power and money above all else. Yet he masks this crudeness behind a civilized demeanor. He seems to have an ability to outlive those around him. The Manager would like nothing more than to surpass Kurtz in the ivory trade and see him dead, so that he would no longer interfere with the competitive trade. He makes people uneasy, and the only explanation Marlow offers is that he is "hollow."
