The best modification of this sentence would be answer choice A. The children were delighted by the acrobats swinging through the air on the stage.
This sentence has the proper structure and the tense and number of the subject/s and verb/s agree. Unlike answer options C and D, the acrobats are still the ones swinging and the children are still the ones delightfully observing in choice A. The reason B is incorrect is because the prepositions are in an awkward order and make he sentence sound choppy. Answer choice A meets all the criteria for a grammatically correct sentence.
