Choose the option that is the most appropriate conversion of the following sentence into Active Voice.

Show answer & explanation
Correct answer: B
Explanation
To convert the passive sentence "The mystery had never been solved by anyone before the detective arrived" into the active voice, the subject performing the action ("anyone," changed to "No one" because of "never") must be placed before the verb. The verb tense must remain past perfect ("had solved") to match the original sentence's timeline.
