The adverb in the given sentence is "well", which is an adverb of manner. It describes the way in which the child performs at the concert. Adverbs modify adjectives, verbs and other adverbs. As it describes the manner in which the child performs, it modifies the verb "performed". Adverbs of manner are usually placed in the end of the sentence or in the mid position (mid position is between the subject and the verb). But when there are more than the three types of adverbs in a sentence, they usually go in the order: manner, place, time. Here, the adverb of place is "in the concert" and the adverb of time is "yesterday night". Hence, the adverb of manner comes first, and not second, as mentioned in the question. Option D has the correct order, hence it's the right option, and A is thus, incorrect. An adverb of manner is not placed before the verb (performed), in some cases it precedes the verb to emphasize it, and here an emphasis is not required. Hence option B is incorrect. Option C does not follow the order of the adverbs of manner, place and time, and it sounds grammatically incorrect, hence option C is incorrect.
