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

Correct option is B

The statement "he loved his parents" is accurately converted to "I love my parents" in direct speech, maintaining the simple present tense indicative of a general truth or state.
Rule of Conversion: Past simple in indirect speech is converted to present simple in direct speech when stating general truths or ongoing emotions. Pronouns and possessives are adjusted to suit direct dialogue.
Example: He told her he loved his job -> He told her, "I love my job."
