The correct answer is C. A small or subtle difference in meaning
Step-by-step explanation:
The word "nuance" refers to a slight or subtle difference in different elements of the same category, for example, a slight difference in two or more colors. In the writing context, a nuance refers to a subtle difference in the meaning of words that made two or more words have a similar but not identical meaning. This can be explained as the literal definition of a word is not the same that the connotation or association a word has or the meaning provided by the context in which a word is used. For example, the words "house" and "home" have the same literal meaning or denotation as they refer to the places where people live, but the word "home" has an association with love, affection, and safety which gives the word "home" a small or subtle difference in meaning or nuance. Considering the previous ideas, it can be concluded a nuance refers to a small or subtle difference in meaning.
