Pronouns refer to the words which replace nouns in a sentence. For example, Alan is a good boy. Alan works hard. Alan is punctual.
Hence, instead of a repetition of noun we use pronouns,
Alan is a good boy. He works hard. He is punctual.
In the following the sentence in which all pronouns are used correctly is C. I sat between him and her during the sales conference.
There is an appropriate use of personal pronouns with the subject pronouns. Whereas in the other sentences like
A. I hope she will keep this between she and I.
- It uses the inappropriate personal pronoun "I" and the subject pronoun "she", instead it should be "her and me."
B. Just between you and I, I am not impressed by our new manager.
-Inappropriate use of the personal pronoun "I", instead it should be, " just between you and me."
D. Be sure to divide all income from the suburban property between he and I.
- It uses the inappropriate personal pronoun "I" and the subject pronoun "he", instead it should be "him and me."
