Final answer:
The speaker implies he does not feel qualified to be king when he states he "felt like a third grader," reflecting a sense of being overwhelmed or unprepared for such a significant role. The correct option is 3.
Step-by-step explanation:
When the speaker says he "felt like a third grader" (lines 17-18), he implies that he does not feel qualified to be king. This feeling can relate to a sentiment of being overwhelmed, inexperienced, or unprepared for the responsibilities associated with being in a leadership position or receiving a significant honor.
The comparison to a third grader suggests a feeling of insignificance or lack of readiness in contrast to what is expected of a person in a royal or highly esteemed position. The correct option is 3.
