The best choice that expresses the narrator's viewpoint towards Jasper is:
- The narrator thinks Jasper is foolish.
While Jasper's loyalty to his brother and his positive thinking can be noted, the overall tone of the narrator suggests a degree of bemusement at Jasper's lack of awareness regarding the challenges he faces. The phrase "doomed voyage" and the description of Jasper as "oblivious" and "a comical sight" indicate a critical perspective on his misguided enthusiasm.
