Symbolism is the use of symbols in order to represent something. Hope in a story refers to the expectation of positive results in spite of difficulties, and with minimum chance of success. It is the certainty that things can get better. With this explained, we can conclude that option C is the correct one, because it kind of represents spring, which comes after winter when the weather is rough but everything after that is nice. Meaning that after rough times there is always something good to see.
