Rewrite the sentence in the direct speech.
Rajesh told Sumithra that he loved his parents.

Correct option is B

The correct option is (b) Rajesh said to Sumithra, "I love my parents".
Tense change: "Loved" in indirect speech becomes "love" in direct speech (present simple).
Pronoun change: "He" becomes "I" to reflect Rajesh's speech in first person.
Time clause change: No specific time clause change is required.
Reporting verb change: "Told" changes to "said to" in direct speech to introduce the quoted speech properly.
Corrected sentence: Rajesh said to Sumithra, "I love my parents".
