The passive form of the sentence 'I had already shown her photo to the policeman" should be: 

প্রদত্ত Active voice এর বাক্যটিতে দেখুন Had আছে আর তারপরে আছে Shown যা Verb এর Past Participle. তাই এই বাক্যটিতে 

Passive করতে হলে Had been আসবে । দেখুন অপশনগুলোর মধ্যে শুধু c) তেই Had been আছে, তাই এটি উত্তর । তাই Passive হলো The 

policeman had already been shown her photo. যার অর্থঃ পুলিশকে ইতিমধ্যে তার ছবি দেখানো হয়েছিলো । 

যেহেতু উত্তর অপশনে that নেই, তাই that ছাড়াই উত্তর হবে She said that she was very late and she had to go.
