Answer:
B. the red blanket
Step-by-step explanation:
Symbol is always something that represents something else. In literature a symbol is something that has a greater meaning than its mere literal significance in a story or a poem. This symbolic meaning may be author-specific or more widespread, ranging from cultural importance to universal association. In the excerpt shown in the question, the symbol is represented by "the red blanket," which represents something more than a simple blanket and has a larger representation within the work.
