The correct answer is B. Intensive
Step-by-step explanation:
In grammar, a pronoun is intensive if it ends in -self or -selves, refers to a noun previously mentioned, and it emphasizes this noun; although it is not essential for the sentence, which means it can be removed without the sentence changing its meaning. These pronouns differ from reflexive pronouns because reflexive pronouns are essential to the sentence. In the case of "Mandy went to look for the missing cat herself" the pronoun "herself" can be classified as intensive because it ends in -self; it emphasizes the noun "Mandy" but it is not essential to the sentence as "Mandy went to look for the missing cat" stills makes sense.
