Choose the correct passive form of the given sentence:
Let us plant a neem tree in the school garden.
Answer & explanation
Correct answer: option 3
The correct answer is Option (3) → Let a neem tree be planted in the school garden by us.
Passive of a “Let us” sentence:
| Change | Active | Passive | Why |
|---|---|---|---|
| Let kept | Let us | Let | The sentence is a suggestion that begins with “Let”. The passive also begins with “Let”. |
| Object becomes subject | a neem tree | a neem tree | The tree receives the action, so it becomes the subject and comes right after “Let”. |
| Verb made passive | plant | be planted | After “Let a neem tree”, “plant” becomes be + past participle (V3): “be planted”. |
| Agent (by ...) | us | by us | “Us” means the speakers. They will do the planting, so the doer comes after “by”. |
| Full sentence | Let us plant a neem tree in the school garden. | Let a neem tree be planted in the school garden by us. |
“Let him” and “Let them” sentences work the same way. Example: Let him sign the form. → Let the form be signed by him.
Why the Other Options are Incorrect?
Option 1: Let a neem tree be plant in the school garden by us. — Incorrect. “Plant” is the base form. After “be”, the V3 “planted” is needed.
Option 2: Let us be planted a neem tree in the school garden. — Incorrect. Here “us” becomes the one that is planted. The tree must come after “Let”, not “us”.
Option 4: Let a neem tree is planted in the school garden by us. — Incorrect. “Is” cannot follow “Let” + subject. “Let” is followed by the subject + “be”.
