Since the sentence uses the subject "we" and the speaker is included, therefore, the correct answer would be first person plural. The correct choice is option A. It is stated in the first person because the speaker is the one who is stating the statement. It is in the plural form because there are other persons along with the speaker doing the action.
In the first-person-plural point of view, narrators tell the story using "we". That is, no individual speaker is identified; the narrator is a member of a group that acts as a unit.
In the subjective case, the singular form of the first person is “I,” and the plural form is “we.” “I” and “we” are in the subjective case because either one can be used as the subject of a sentence. You constantly use these two pronouns when you refer to yourself and when you refer to yourself with others
