Concept:The task requires choosing the word that is the closest opposite of the underlined word "disgusting" and also fits correctly into the given sentence.
Explanation:The word "disgusting" means something that causes strong dislike or revulsion.
Therefore, the missing word should express the opposite meaning, that is, something agreeable or pleasing.
Option C, "pleasant," means enjoyable or satisfactory, which directly contrasts with "disgusting."
Option A, "refreshing," means restoring energy or vitality; it does not serve as a direct opposite here.
Option B, "medicinal," refers to something having healing properties, which is unrelated in meaning.
Option D, "bitter," describes a sharp, unpleasant taste and is not the opposite of "disgusting."
Thus, "pleasant" is the only word that creates the correct contrast and makes the sentence meaningful.
Answer:C. pleasant
