The correct option is C her, She, her, He, her
The first sentence refers to a female as the object, hence, "her". The second refers to the female as the subject, hence, "she". The third part refers to a female as the object, hence, "her". The fourth refers to the male boss as the subject, therefore, "he". The fifth part refers to a female subordinate as the object of the sentence, therefore, "her". Hence, Option D is correct. The rest of the options do not adhere to this rule, hence incorrect.
