Personal pronouns are used to replace people, places or things to make sentence shorter and clearer. Examples of personal pronouns include I, we, it, they, you, she.

The correct answer is: We

    The pronoun 'we' is the first-person plural pronoun. 'We' is used as the subject of a verb. A speaker uses 'we' to refer both to himself or herself and to one or more other people as a group. 'My mom, dad and I went to the beach', here you can use 'we' to refer more other people as group.
