Correct Answer: The team leader congratulated us and said that we had prepared a very good presentation.

Solution : The correct answer is the second option.

Indirect speech, also known as reported speech or indirect discourse, is a way of reporting what someone else has said without quoting their exact words.

Narration conversion:

• The exclamatory sentence is changed to an assertive sentence by using the reporting verb "congratulated".
• The second-person pronoun "you" is changed to the first-person pronoun "we".
• The present perfect tense "have prepared" is changed to the past perfect tense "had prepared".
• The phrase "and said" appropriately connects the actions.

Therefore, the correct answer is: The team leader congratulated us and said that we had prepared a very good presentation.
