Final answer:
Americans spent about 17% of the GDP on health care as of a 2019 context, reflecting an increasing trend in health care expenditures compared to other countries. However, this option is not given in question. So, either option is missing or we can take the answer to option (c) 15% which is nearest to 17%.
Step-by-step explanation:
According to the data sourced, specifically from a 2019 context, Americans spent approximately 17% of the total gross domestic product (GDP) on health care. This reflects how the United States is an outlier compared to other countries in terms of health care spending, which is notably higher.
Although the data from the 2010 Statistical Abstract is not directly quoted, related sources indicate that health care spending as a percentage of GDP has been increasing over time. Given the projected growth in healthcare spending and the historical trend of increasing healthcare expenditures relative to GDP, the 17% figure provides a reasonable reference point for discussion around the time this data was relevant.
