Which is the correct passive voice of the following sentence?
They have painted the door.

Question

Accepted Answer

The sentence "They have painted the door" is in the active voice, where "They" is the subject performing the action of painting, and "the door" is the object receiving the action. To convert this sentence into the passive voice, the focus shifts from the subject to the object, and the verb form is adjusted accordingly.

1. **Explanation for Option 2: "The door has been painted"**
   - This option correctly transforms the active voice sentence into the passive voice. In the passive construction, the object of the active sentence ("the door") becomes the subject of the passive sentence. The present perfect tense "have painted" is converted to "has been painted" in the passive voice. This maintains the tense and meaning of the original sentence while shifting the focus to the door, which is the recipient of the action. Therefore, Option 2 is the correct passive voice transformation.

2. **Explanation for why other options are incorrect:**

- **Option 1: "The door was painted"**
     - This option uses the past simple tense "was painted," which does not match the present perfect tense of the original sentence. The original sentence indicates that the action has relevance to the present, which is not conveyed by the past simple tense. Therefore, this option is incorrect.

- **Option 3: "The door is painted"**
     - This option uses the present simple tense "is painted," which suggests a general state or habitual action rather than a completed action with present relevance. The original sentence's present perfect tense indicates a completed action with current significance, which is not captured by the present simple tense. Thus, this option is incorrect.

- **Option 4: "The door be painted"**
     - This option is grammatically incorrect as it does not form a proper passive voice sentence. The structure "be painted" lacks the necessary auxiliary verb to indicate tense and does not convey the completed action implied by the original sentence. Therefore, this option is incorrect.

In conclusion, Option 2, "The door has been painted," is the correct passive voice transformation of the given active voice sentence, as it accurately reflects the tense and meaning of the original sentence while focusing on the object of the action.
