Which option exemplifies a reversible passive sentence?

In a reversible passive sentence, the subject and object can be switched while maintaining a logical structure, indicating that the action can be performed in both directions. The example of Jared being bullied by Michael shows that the sentence can be reversed. It suggests that Michael performed the action of bullying on Jared, and one could also say that Jared was the one being bullied by Michael.

For instance, one could switch the subjects to form a new sentence: "Michael bullied Jared." This switch maintains the meaning, illustrating the reversibility of the action. Other sentences listed, while being passive, do not allow for a logical reversal in the same way. For example, "The balloon was broken by the pin" implies that the pin caused the balloon to break, but does not make sense if reversed as “The pin was broken by the balloon.”

Thus, option C distinctly captures the essence of a reversible passive sentence, highlighting the mutual action between the individuals.
