From the given alternatives, choose the one which best expresses the sentence in Active/Passive voice.
You need to clean your dishes properly.

Your dishes need to be cleaned properly.

The correct answer is Your dishes need to be cleaned properly.

The original sentence is in active voice, with the subject "you" and the verb "need". To change it to passive voice, we make the object of the active sentence, "dishes", the subject of the passive sentence. The verb "need" becomes "need to be cleaned", and we do not add the preposition "by" because the subject of the active sentence is not mentioned in the passive sentence. This gives us the passive voice sentence "Your dishes need to be cleaned properly".

The other options are incorrect.

• Your dishes are needed to clean properly is in active voice, but it changes the meaning of the sentence. The original sentence means that you need to clean your dishes properly, but the active voice sentence means that your dishes need to be cleaned properly by someone.
• You are needed to clean your dishes properly is also in active voice, but it is not grammatically correct. The verb "need" does not take a direct object, so it cannot be used with the preposition "to".
• Your dishes are needed by you to clean properly is also in active voice, but it is not grammatically correct. The preposition "by" should not be used with the verb "need".
