Answer: Maria
Step-by-step explanation:
The pronoun "she" in the sentence is unclear because it can be confusing as to who the pronoun is referring to as Dr. Jasmine could either be referring to herself or to Maria.
The correct word might be Maria's name itself so that anyone reading the sentence can have no doubt in their mind that Maria is the subject of the discussion.
The sentence would then be;
Dr.Jasmine Carr told Maria and her parents that Maria would have to get braces.
