Solution:
The correct option is A) ‘I’. The words that are used in place of a noun are pronouns. According to English grammar, a pronoun cannot be used until and unless a noun has been mentioned or used beforehand. Pronouns can be of various types based on their usage, such as: personal, reflexive, emphasising, possessive, relative, demonstrative, indefinite, and interrogative. Reflexive pronouns are those which show that the actions done by the subject reflect back to them, such as herself, myself, himself, ourselves, etc. Therefore, the required answer is (A) I, as it is a personal pronoun instead of reflexive.
