Identify the error in the following sentence.
Ourselves should not boast of one’s knowledge.

Correct option is C

Option (c) contains an error.
· The word "Ourselves" is a reflexive pronoun and cannot be used as the subject of a sentence. Reflexive pronouns are used when the subject and object of the sentence refer to the same entity.
· Instead, "We" should be used in place of "Ourselves" for correct sentence formation.
· Corrected sentence: "We should not boast of one’s knowledge."
Grammatical rule used:
· Reflexive pronouns (myself, yourself, himself, herself, itself, ourselves, yourselves, themselves) are used only when the action reflects back on the subject, not as the subject itself.
· Example: "I hurt myself while playing football." (Correct use of reflexive pronoun)
