Which choice displays correct use of both parallel structure and commas? A) The following items were in the refrigerator: milk,
cheese, bread, and soda. B) The following items, were in the refrigerator: milk, cheese, bread, and soda. C) The following items were in the refrigerator: milk, cheese, there was bread, and soda. D) The following items were in the refrigerator: milk, cheese, bread, and we also had soda.
The correct sentence is (A). In this example the author stablishes a good parallel structure when he/she enumerates the items. Commas must not be used in an independent clause; in particular, before a verb (the comma before “were” is not correct as an example B).
