Correct Answer: Ramu said that lots of people in his village had helped the migrant workers by giving them food.

Solution : The fourth option is the correct answer.

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:

• Since "Ramu" is the speaker, the possessive pronoun should be changed from "my" to "his" in reference to "village".
• The present simple tense "helped" remains unchanged, as the reporting verb "said" is in the past tense.
• The other elements, like "lots of people in his village" and "by giving them food" are retained to maintain the original meaning.

Therefore, the correct answer is: Ramu said that lots of people in his village helped the migrant workers by giving them food.
