  3. C
    Ought the crucial evidence to has been turned over to the prosecuting counsel by the lead investigator before trial?
  4. D
    Ought the crucial evidence to be turned over to the prosecuting counsel by the lead investigator before trial?

Answer

Ought the crucial evidence to have been turned over to the prosecuting counsel by the lead investigator before trial?
The correct passive sentence maintains exact structural alignment with the active question: the interrogative modal 'Ought' leads the sentence, followed by the new subject ('the crucial evidence'), the passive modal perfect auxiliary sequence ('to have been turned over'), the prepositional complement, the agent ('by the lead investigator'), and the temporal modifier. Crucially, the phrasal particle 'over' is preserved.

Step-by-Step Solution

1
Identify the active subject, verb phrase, direct object, and auxiliary structure.
Subject: 'the lead investigator'; Verb phrase: 'ought to have turned over' (modal verb 'ought' + perfect infinitive 'to have turned' + phrasal particle 'over'); Direct object: 'the crucial evidence'.
Accurate grammatical identification is required before re-ordering clause elements.
2
Promote the active direct object to the passive subject position following the interrogative modal.
The structure becomes 'Ought the crucial evidence...'
In passive interrogatives, the primary auxiliary verb remains at the front while the new subject follows it immediately.
3
Convert the active perfect verb phrase into its corresponding passive perfect form while retaining phrasal verb particles.
'to have turned over' becomes 'to have been turned over'.
The passive form of a modal perfect infinitive requires 'to have been' + past participle, and phrasal verb particles must be strictly retained.
4
Attach the agent prepositional phrase and remaining adjuncts.
'...to the prosecuting counsel by the lead investigator before trial?'
Preserves complete semantic information and thematic roles of the original sentence.
