Final answer:
3) Daenerys Targaryen. To reduce ambiguity in the sentence, the pronoun 'she' should be replaced with 'Daenerys Targaryen'.
Step-by-step explanation:
In the second sentence, the pronoun 'she' is being used to refer to a character. To reduce ambiguity and make the sentence clearer, the pronoun 'she' should be replaced with 'Daenerys Targaryen', which is the character's name. By using the character's name, it ensures that there is no confusion about who the pronoun is referring to. Daenerys Targaryen would be the correct choice to replace the pronoun 'she'.
