Answer: c. Jane said to me, “ I waited for my friend.”
Explanation:
Direct speech is meant to report the things said by a person in the exact way that they said it.
One reason option A is wrong is that Jane said she had waited for the friend which made it past tense but in option A she was using a future continuous tense.
One reason option B is wrong is that it made it seem as though Jane was waiting for the speaker's friend not her own. For this same reason option D is wrong as well.
Option C is correct because it properly converts the indirect speech used by the speaker to direct speech.
