Final answer:
Balboa's desire to be perceived as a lion, despite being a rat, reveals that his character is deceptive, as he is intentionally misleading others about his true nature.
Step-by-step explanation:
The character Balboa is described as a rat who wishes to be seen as a lion. This description indicates a contrast between how Balboa actually is and how he wants to be perceived. Given the options provided, the character trait that best fits this scenario is deceptive.
If Balboa is trying to appear as something he is not, it suggests that he is intentionally misleading others about his true nature, i.e., his character is deceptive. Choosing to present oneself as a brave and noble lion when one is in fact a rat demonstrates a purposeful act of deception.
