Correct option is A
In indirect speech, we typically report what was said without using quotation marks. The correct transformation involves changing the direct command into a reported speech format while adjusting the pronouns and verb tense as necessary.
(A) "The director requested Rajesh to complete the work before he left the office." This is the correct transformation because it maintains the meaning, changes "please" to "requested," and uses the appropriate past tense ("left").
(B) "Rajesh was asked by the director to complete the work before leaving the office." While this is grammatically correct, it changes the structure and doesn't convey the original polite request as effectively as option (A).
(C) "Rajesh, complete the work before you leave the office, the director said." This is a mix of direct and indirect speech and is not the correct form.
(D) "The director told Rajesh to complete the work before leaving the office." Although correct in structure, this changes the tone from a request to an imperative statement, which is not as faithful to the original direct speech as option (A).
