• C. The bridge ought to have been repaired by them long ago
• D. The bridge ought to have been repaired long ago by them

Answer 1

Answer:

B. The bridge ought to have been repaired long ago

• Subject: They
• Verb: ought to have repaired
• Object: the bridge
• Convert the Object of the Active Voice into the Subject of the Passive Voice:
• • Active Voice: They ought to have repaired the bridge.
  • Passive Voice: The bridge ought to have been repaired...
• Change the Verb Form to Passive:
• • "ought to have repaired" becomes "ought to have been repaired"
• "The bridge ought to have been repaired by them long ago." is also correct but less commonly used.
