Correct Answer: The principal applauded that Sonu had performed well and declared that he had won the competition.

Solution : The correct choice is the second option .

Narration Conversion:

• The verb said is changed to applauded , as it is an imperative sentence.
• The second-person pronoun you is changed to Sonu to reflect the shift from the principal's perspective to the reported perspective.
• That is used to introduce the reported clause.
• The present perfect tense "have won" is changed to the past perfect tense "had won" in the reported speech.

Therefore, the indirect speech is: The principal applauded that Sonu had performed well and declared that he had won the competition.
