Select the correct Active/Passive form of the given sentence.
The envelope has not been opened by anyone.
Answer & explanation
Correct answer: option 3
The correct Active/Passive form of the given sentence is:
☀ No one has opened the envelope.
Explanation for other options:
☀ Anyone has not opened the envelope. This option changes the word order, but it is still in the active voice, not the passive voice. The correct passive form should have the subject "the envelope" as the receiver of the action.
☀ No one has not opened the envelope. This option is a double negative and grammatically incorrect. The correct form should be "No one has opened the envelope."
☀ No one opens the packet. This option is in the active voice and is unrelated to the original sentence. It does not convey the same meaning as the original sentence in the passive voice.
