Correct option is D

The correct passive form of the sentence "The class teacher was taking the children to the zoo" is "The children were being taken to the zoo by their class teacher."
· Active Voice- Active voice is a grammatical structure in which the subject of the sentence performs the action expressed by the verb.
· Passive Voice- Passive voice refers to a grammatical construction where the subject of a sentence undergoes an action rather than performing it. In passive voice sentences, the emphasis is on the recipient or object of the action.
· This passive construction appropriately reflects the past continuous tense of the active voice, placing the focus on the children as the recipients of the action, with the class teacher performing the action.
· Example: The tourists were being guided through the museum by the expert, similarly shifting focus from the actor to those affected by the action in a passive voice transformation.
· Other options:
· (a) The children will go to the zoo by their class teacher and (b) The children can be taking to the zoo by their class teacher are grammatically incorrect and misrepresent the tense and mood.
· (c) The children being taken to the zoo by their class teacher lacks the correct auxiliary verb to complete the passive form.
