Final answer:
Option B, which criticizes the self-seeking nature and lack of vision of some leaders, reflects a critical tone from FDR's first inaugural address.
Step-by-step explanation:
The section from FDR’s first inaugural address that reflects a critical tone is option B: “They know only the rules of a generation of self-seekers. They have no vision, and when there is no vision the people perish.” This excerpt criticizes those in power who lacked the foresight and selflessness needed to lead the country effectively. The language used conveys a sense of disappointment and rebuke, which stands in contrast to the other sections that are more focused on positive action and cooperation.
