Which example shows the correct transformation to passive voice?

1. She sang a song

2. A song will be sung by her

3. She will sing a song

4. She had sung a song

The correct answer is: A song will be sung by her

The transformation of a sentence to passive voice focuses on making the object of the action the subject of the sentence, while the original subject may either be omitted or included later in a prepositional phrase. In the provided example, "A song will be sung by her," the sentence transitions from an active structure to a passive one by placing "a song" at the forefront. This reflects the main point of a passive voice construction, where the action of the verb is emphasized over the doer (the performer of the action). In this case, "will be sung" indicates the action in the future tense, and "by her" identifies who is performing the action, thus maintaining clarity about the subject's role while adhering to the passive voice structure. Other examples either remain in the active voice or do not follow the required transformation, making option B the clear representation of passive voice.
