Answer:
d). Helen and Evan went to see the movie, and it was a very good movie.
Step-by-step explanation:
The last sentence i.e. 'Helen and Evan...good movie' demonstrates faulty coordination as the second clause linked through the coordinating conjunction 'and' employs a wrong antecedent 'it.' 'It' is a singular pronoun which is incorrectly used to refer to the plural noun 'Helen and Evan.' Another error in the sentence is that the first clause talks about 'Helen and Evan' while the second clause abruptly shifts to the movie which puzzles the meaning of the sentence. Hence, it is erroneous coordination and therefore, option d is the correct answer.
