Answer:
B. I treasure the brooch, but it is not my most valued possessions.
Explanation:
"The Courage that My Mother Had" (1949) is an elegy written by Edna St. Vincent Millay (1892-1950) to honor her mother. Millay was an American poet and playwright.
The meaning of the given line is captured by statement in option B. The first line "I have no thing to treasure more:" clearly shows that she treasures nothing more than the golden brooch, meaning the brooch is very important and precious to her. The second line"yet, it is something I could spare." contradicts the first statement by saying that she could still spare the brooch, meaning she could let the brooch go (if need be).
Options A and D are incorrect because they are opposite of what is said in the first part of the given line.
Option C is incorrect because there is no mention of courage and its value in the given line.
