The correct answer is C. You told me that you were going to America.
The sentence “You said to me, ‘I am going to America'” is in the direct form. In the direct form, the speaker’s words are quoted exactly. The indirect form is used to report what someone said without quoting their exact words. In the indirect form, the verb “say” is used with a different tense, and the pronouns may be changed.
In this case, the indirect form would be “You told me that you were going to America.” The verb “said” is changed to “told,” and the pronoun “me” is used instead of “I.”
The other options are incorrect because they do not use the indirect form correctly. Option A, “You told me that I was going to to America,” is incorrect because the word “to” is unnecessary. Option B, “You said me that you were going to America,” is incorrect because the pronoun “me” is used after the verb “said.” Option D, “You told me I was going to America,” is incorrect because the verb “told” is used in the wrong tense.
