Answer: A) pleasing to the ear.
Explanation: The connotation of a word is the meaning given by the context or even by the readers (or listeners) based on their emotions or personal experiences. It is the contrary to denotation, which is the literal meaning of a word. The denotation of sweet is related to taste, but in this case the connotation used in the sentence is the corresponding to option A: pleasing to the ear.
