The correct option is: Mother told her that she had expected a better result from her.

• Mother told her that she expected a better result from her. - This sentence does not change the present tense to the past tense for the auxiliary verb "had."
• Mother told her that she was expecting a better result from you. - This sentence uses the present continuous tense for the reported speech, which is incorrect in indirect speech.
• Mother told her that she expected a better result from you. - This sentence does not change the second person pronoun "you" to the third person pronoun "her."
