Final answer:
The best-supported statement about Lord Blackheart is that he wasn’t allowed to become a hero after losing his arm, as this is the closest conclusion we can draw from the provided excerpts by excluding the other options. The corrct option is d).
Step-by-step explanation:
Based on the excerpts provided, we can deduce that Lord Blackheart is a complex character with various traits and motivations. However, based on the choices given, the statement that is best supported by the excerpt is: d) He wasn’t allowed to become a hero after losing his arm.
There is no direct evidence in the text provided that indicates he lost his arm while saving Sir Goldenloin’s life, that he became a villain to please his father, or that he was too reckless and arrogant to become a hero.
Instead, the excerpts focus on his heroic qualities and noble actions which contradict the choices that he became a villain or was reckless and arrogant.
Therefore, by exclusion of the other options, the closest conclusion is that something occurred with his arm that may have prevented him from becoming a hero, as implied by option d.
