Select the option that expresses the given sentence in passive voice.
The interference of the police force would have controlled the situation.

Correct option is A

The correct passive voice of the given sentence is (a) The situation would have been controlled by the interference of the police force.
Explanation:
· In passive voice, the object of the active sentence becomes the subject of the passive sentence.
· The structure for changing "would have controlled" in active to passive voice is:
Active Voice: Subject + would have + V3 (past participle) + Object.
Passive Voice: Object + would have been + V3 (past participle) + by + Subject.
· Applying this:
· Active: The interference of the police force would have controlled the situation.
· Passive: The situation would have been controlled by the interference of the police force.
Incorrect Options:
· (b) "Could be controlled" - incorrect as it changes the tense.
· (c) "Could have been controlled" - incorrect as "could" does not match the original modal "would have".
· (d) "Would be controlled" - incorrect as it alters the tense and meaning.
