Concept: A passive of the form should have been + V3 becomes should have + V3 in the active voice; the modal and the perfect sense must stay.
- The agent is not given, so the doer is understood as you.
- should have been placed → should have placed.
- (A) and (C) lose the perfect sense (a past duty that was not done); (B) changes the modal to will.
Yaad rakhein: should have been + V3 ↔ should have + V3 – only been is dropped.
Answer: (D) You should have placed the books on their proper shelves.
अवधारणा: should have been + V3 वाला passive, active में should have + V3 बनता है; modal और perfect भाव वही रहते हैं।
- Agent नहीं दिया है, अतः कर्ता you माना जाएगा।
- should have been placed → should have placed।
- (A) और (C) में perfect भाव (अतीत का अधूरा कर्तव्य) खो गया; (B) में modal will कर दिया गया।
याद रखें: should have been + V3 ↔ should have + V3 – केवल been हटता है।
उत्तर: (D) You should have placed the books on their proper shelves.
