Change the following sentence into the Active form.
The report, which should have been submitted by the deadline, was delayed due to unforeseen circumstances.
Show answer & explanation
Correct answer: D
Explanation
The original sentence, "The report... was delayed," is in the passive voice because the subject (the report) receives the action. To change it to the active voice, the subject performing the action (They/Unforeseen circumstances) must come before the verb. Option D correctly identifies the actors ("They" and "unforeseen circumstances") and uses active verb structures ("should have submitted", "delayed") to convey the meaning clearly.
