Fill in the blank with the correct passive verb form:
Plants _________ by the gardener every evening.
An action in a sentence can be represented in two ways, namely active and passive voice.
The passive voice always uses the past participle form of the main verb irrespective of any tense. Only the auxiliary verbs depend upon the sentence given in active voice.
The correct answer is C) Are Watered as the passive verb should be in its third form.
Options A, B and D are not correct as the given sentence is not in the present continuous form and 'plants' are plural respectively.
Plants are watered by the gardener every evening.
