Change the Voice: The boy did not break the glass.

The glass was not broken the boy.

The glass had not broken the boy.

The glass is not broken the boy.

None of these

The original sentence is in the active voice, and the correct conversion to the passive voice is:

"The boy did not break the glass" → "The glass was not broken by the boy"

This changes the focus from the doer (the boy) to the receiver (the glass).
