The correct answer is: E. No correction required.
The sentence “They were all charmed by the sweet and soothing music” is grammatically correct and conveys the intended meaning. The adjective “sweet” describes the music as being pleasant and pleasing to the ear. The adjective “soothing” describes the music as being calming and relaxing. The two adjectives are used together to create a compound adjective that describes the music as being both pleasant and calming.
Option A, “sweet and soothingly,” is incorrect because it uses the adverb “soothingly” instead of the adjective “soothing.” The adverb “soothingly” describes how something is done, while the adjective “soothing” describes the thing itself. In this case, we are not interested in how the music is being played, but rather in the fact that it is soothing.
Option B, “sweetly and soothing,” is incorrect because it uses the adverb “sweetly” twice. The adverb “sweetly” describes how something is done, and in this case, it is being used to describe both the music and the people who are listening to it. This is redundant, and it is not necessary to use the adverb twice.
Option C, “sweetened and soothing,” is incorrect because it uses the verb “sweeten” instead of the adjective “sweet.” The verb “sweeten” means to make something sweeter, while the adjective “sweet” describes something that is already sweet. In this case, we are not interested in making the music sweeter, but rather in the fact that it is already sweet.
Option D, “sweetly and soothing,” is incorrect because it uses the adverb “sweetly” twice. The adverb “sweetly” describes how something is done, and in this case, it is being used to describe both the music and the people who are listening to it. This is redundant, and it is not necessary to use the adverb twice.
