Question

Which pronoun best completes the sentence how was the pronoun used Mr.peters sat between Molly ___

Answer 1

Mr. Peters sat between Molly and me.  The pronoun "me" is correct because it is an objective case pronoun.  If a pronoun is used as the object of a preposition, an objective case pronoun must be used.  "I" would not be correct because it is not an objective case pronoun.
