Which sentence demonstrates correct subject-verb agreement? (a)the balloon gone away above the clouds and out of sight.(b)he and jason went to the school play last weekend.(c)yesterday, he goes to the store for milk and bread.(d)casey and her parents gone on the tour on tuesday. i need a answer asap

type of error:

the error in the sentence is a "dangling modifier". a dangling modifier is a phrase, word or clause that "dangles" because there is not target to modify. in this case, "after mopping the floor" is the dangling modifier since it has no word to modify. the noun "house" cannot mop the floor; therefore there is a mistake in the writing of the sentence.
