Answer and Explanation:
Even though you didn't highlight any parts of the sentence, I believe it is still possible to answer it. This type of sentence commonly has an unclear pronoun in its second part, in this case "that she would have to get braces." Who is the "she" that would have to get braces? Two people were mentioned in the previous part of this sentence that could be referred to by "she": Dr. Jasmine Carr and Maria. Since Jasmine Carr is the doctor, we can safely assume that she is the one communicating the fact that Maria needs braces. In that case, to eliminate the ambiguity in the sentence, we simply substitute "she" for "Maria":
Dr. Jasmine Carr told Maria and her parents that Maria would have to get braces.
