Answer:
A). Evidential support, such as facts, figures and statistics.
Step-by-step explanation:
The central claim of the given paragraphs is displayed when the author describes that people are landing in bankruptcy due to a lack of health insurance which exemplifies a financial burden. In order to substantiate his claim, the author uses certain pieces of evidence like data('uninsured people have poor health status'), figures('50% of people'), statistics('Jacoby, et al., 2000') which supports his argument positively and effectively. Thus, option A best supports the author's central claim that describes the lack of health insurance as a financial burden.
