The correct option is B clumsiness
Elegance means the quality of being graceful and stylish in appearance or manner. The opposite of elegance is the quality of being awkward or careless in one's movements, that is, clumsiness. Hence, Option C is correct. Among the rest of the options, awkwardness means a feeling of self-consciousness, shame, indelicacy means a lack of sensitive understanding or tact, savagery means the quality of being fierce or cruel. These options do not express this antonym, hence incorrect.
