Answer: The tourist said (that) India was a very beautiful country.
Explanation: To convert to reported speech, you will have to change certain words in the sentence as it is now in past tense.
Some words need to be changed to past tense. In this case, we change the word 'is' to 'was'.
We also need to remove the speech marks as it is now in past tense.
Sometimes, we can also use the word 'that' to introduce the reporting verb (said) in reported speech.
So, the answer can be:
The tourist said India was a very beautiful country.
or...
The tourist said that India was a very beautiful country.
Either way should be correct.
Hope this helps!
