We can see here that the statement that best describes how Liz is characterized in paragraphs 24-25 is: C. Liz is not wealthy, but does her best to present herself nicely.
Her clothing was described as "well-fitting and not without style" (Paragraph 24) in the text. Her clothing fit her well and have style rather than being outdated, which indicates that she attempts to dress as best she can.
But the passage also reveals that "her shoes were strangers to polish, and were run down over twisted high heels" (Paragraph 24). This demonstrates that she makes the most of what she has and does not have a lot of money to buy new things.
