Rewrite the sentence in Direct Speech.
The officer told his peon that he was not efficient.

Correct option is B

Definition:
Direct speech reinstates the speaker’s words exactly as they were spoken.
In indirect speech, such statements get converted into reported format with tense/pronoun changes.
The correct direct speech form of the sentence is (b) The officer said to his peon, 'You are not efficient'.
Explanation: In the indirect speech, “The officer told his peon that he was not efficient,” the verb "was" is in the past tense, which in reported speech likely came from the present tense “are” in the original direct speech. When converting to direct speech, we reverse the backshift and also change the pronoun “he” (referring to the peon) to “you,” as the officer is directly addressing the peon.
Grammatical rule used:
When converting indirect speech with a past reporting verb and a general truth or present state, it is often originally in the present tense. Also, pronouns change as per speaker and listener.
Explanation of the grammatical rule in Hindi:
अगर reported speech में कोई सामान्य सत्य या स्थायी स्थिति हो, तो indirect speech में वह past में लिखा जाता है, लेकिन direct speech में वह present tense में रहता है। “he was not efficient” indirect का direct होगा “you are not efficient”.
Example:
Indirect: She told me that I was careless.
Direct: She said to me, “You are careless.”
