Correct Answer: Mother told Ravi to wash his hands before eating.

Solution : The third option is the correct choice.

The given sentence is a direct speech, and we need to convert it into an indirect speech.

We will follow these rules for direct-to-indirect speech conversion:

• The reporting verb "said to" changes to "told" in indirect speech.
• The pronoun "your" (second-person pronoun) changes to "his" (third-person pronoun) in indirect speech.
• The infinitive form of the verb is used in the case of imperative sentences in the reported speech.
• This conversion maintains the imperative nature of the sentence.

Therefore, the correct answer is: Mother told Ravi to wash his hands before eating .
