Answer:
Rana told her that she will follow her.
Step-by-step explanation:
Changing a speech from the direct to the indirect form requires certain changes to the sentence. This includes removing the quotation marks/ speech marks, then replacing the pronouns as required. Moreover, the tense of the speech will depend on the frame of the sentence.
In the given direct speech, the "I" refers to Rana, and the "you" in her speech means the girl she's talking to. Thus, the indirect speech for the given sentence will be-
Rana told her that she will follow her.
We change the "shall" of the speech because shall is used for first-person whereas in the indirect speech, the I becomes "she" as it refers to Rana.
Thus, the correct sentence is
Rana told her she will follow her.
