Correct option is A
The correct passive form of the sentence “My father shall write me a letter” is (a) A letter will be written to me by my father.
Detailed Explanation (English): Active voice: My father shall write me a letter.
· Subject → My father
· Verb → shall write
· Indirect object → me
· Direct object → a letter
When converting to passive voice, the object (a letter) becomes the subject of the sentence. The structure for simple future passive voice is: will/shall + be + past participle (V³)
Therefore: A letter will be written to me by my father.
Grammatical rule used: In Simple Future Tense, the passive voice is formed using will/shall + be + V³. When a verb takes two objects (direct and indirect), either object can become the subject in the passive voice.
Explanation of the grammatical rule in Hindi: Simple Future में passive voice बनाने का नियम है — will/shall + be + क्रिया की तीसरी रूप (V³)। यदि किसी वाक्य में दो objects हों (जैसे “me” और “a letter”), तो किसी एक को subject बनाया जा सकता है। यहाँ मुख्य वस्तु “a letter” है, इसलिए वाक्य होगा — A letter will be written to me by my father.
Example:
· Active: She will send me a gift.
· Passive: A gift will be sent to me by her.
