Final answer:
Based on the given information, the answer to the question would be either option B (15%) or option C (20%).
Step-by-step explanation:
The question is asking about the percentage of women living on their own in late adulthood who live on an income below the poverty line. According to the given information, the poverty rate among the elderly in the United States was 14% in 2010. While this statistic includes both men and women, it provides a general idea of the poverty rate for the elderly population. Based on this information, it is reasonable to assume that the percentage of women in late adulthood living on their own and below the poverty line would be similar or slightly higher. Therefore, the answer to the question would be either option B (15%) or option C (20%).
