Answer:
C). The writer wants to conceal the identity of the person who broke the jar.
Step-by-step explanation:
As per the question, the best explanation or justification for revising the given sentence to passive would be that 'the writer intends to hide/conceal the identity of the person who broke the jar'. The conversion of the sentence into passive would shift the focus from the subject to object and emphasize the action of 'breaking' and the object that was broken 'jar' instead of the doer which is the primary aim of employing passive voice. The subject becomes the recipient who could be omitted from the sentence(in passive voice to hide the identity of the doer). Thus, option C is the correct answer.
