n indirect speech, the original speaker's words are reported while adjusting pronouns and tenses as necessary to fit the reporting context. The original direct speech is, "Congratulations! You have done well."

Option (4), "He congratulated him and added that he had done well," accurately conveys the meaning of the original sentence. It reports the congratulatory message and changes the pronouns to match the reported speech's subject and object. The use of "had done well" is in the past tense to align with the indirect context.

Options (1), (2), and (3) either do not accurately report the message or do not adjust the tenses and pronouns correctly to match the indirect speech context.
