Final answer:
The woman's character is best described as independent, eccentric, and nervous, which aligns with the traits presented across the different passages.
Step-by-step explanation:
The character described across the different passages seems to manifest a variety of traits. From the description, she appears to possess an inner strength and self-reliance, suggested by having nourished herself 'wholly from within' and being 'altogether happy' in her solitude in New York. These traits align closely with Option C, independent, while her early confidence and comfort in her own company could be seen as signs of eccentricity. The passages also allude to moments of internal struggle or nervousness, such as the sight of the 'sob came up into her throat' and her 'dull stare'. Ultimately, the most fitting answer seems to be 'C. independent, eccentric, nervous' as these terms encapsulate the complexity of the woman's character across the varied aspects mentioned in the texts.
