The correct answer is: 'She exclaimed that it was a very beautiful painting.' Exclamatory sentences in direct speech become statements with 'exclaimed' in indirect speech. We remove the exclamation mark and restructure the sentence. The adjective 'beautiful' remains but the exclamatory structure changes. Example: Direct: 'How wonderful!' he cried. Indirect: He cried that it was wonderful.
