Correct Answer: I said to him, “If you go around the park you will see some rare flowers.”

Solution : The correct choice is the fourth option.

Converting indirect speech to direct speech involves changing the pronouns, verb tenses, and sometimes word order.

The steps of conversion are as follows:

• The reporting verb "told" is changed to "said".
• The third-person pronoun "he" is changed to the second-person pronoun "you".
• The past simple tense "went" is changed to the present simple tense "go".
• And "would" is changed to "will" in the conditional part of the sentence.
• The words of the speaker are enclosed in the inverted commas.

So, the correct sentence would be: I said to him, "If you go around the park, you will see some rare flowers."
