A pronoun is a word that is used as a substitute of a noun. In a sentence, the form of pronouns vary according to to three kinds of persons (first, second and third), two kinds of number (singular and plural), and four kinds of gender(masculine, feminine, neuter and common).

The correct answer is: We

    The correct answer is "we".
    From the above-mentioned example, we can say that the speaker along with his friends went to the church. Here, the subject is both the speaker and his friends and to represent it, we must use a first person plural number pronoun. Among the given options, only the word "we" has a similar feature. So, the correct answer is "we".
