· 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 transformation succinctly converts the passive inquiry into its direct active form, maintaining the simple past tense and directly addressing the action of writing.

· (c) "Who write this poem?" uses an incorrect verb tense and form.
