There are two types of speeches in the English language: Direct Speech and Indirect Speech.

• In direct speech, the exact words of the narrator are quoted in commas as in the sentence above.
• When changing direct speech into indirect or vice versa, the tense structure changes(except if the narrator speaks in present indefinite, the tense doesn't go under any change.
  
  
  Thus, option C is correct.
