Choose the correct ‘Passive voice’ of the following ‘Active voice’: “Please don’t smoke.”

The correct option is "ঘ: You are requested not to smoke" because it correctly converts the imperative sentence "Please don’t smoke" into a polite passive form. This phrasing maintains the request's polite nature while shifting the focus from the direct command to a more passive and courteous tone. The other options either change the meaning or are not accurate representations of the original sentence.
