From the given alternatives, choose the one which best expresses the sentence in Active/Passive voice.
North-East grows tea.

Tea is grown in North East.

The correct answer is Tea is grown in North East.

The original sentence is in active voice, with the subject "North-East" and the verb "grows". To change it to passive voice, we make the object of the active sentence, "tea", the subject of the passive sentence. The verb "grows" becomes "is grown", 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 "Tea is grown in North East".

The other options are incorrect.

• Tea is being grown in North-East is in the progressive passive voice. This sentence is used to describe an action that is happening in the present. The original sentence does not describe an action that is happening in the present.
• Let the tea be grown in North East is in the imperative passive voice. This sentence is used to give a command or make a request. The original sentence is not a command or a request.
• Tea grows in North East is in active voice. The subject of the sentence is "tea", but the verb "grows" does not have an object. This sentence is not grammatically correct.
