Identify the sentence written in passive voice: 

you are requested to complete the project

The correct answer is Option (3) - you are requested to complete the project

• In the passive voice, the object of the action becomes the subject of the sentence, and the subject (the doer of the action) is either omitted or included after "by."
• In this case, "You are requested" is the passive form, where the focus is on the action being requested rather than who is doing the requesting.
