Right Answer is: D
Basic rules to be followed for Active/Passive conversions are:
1. The object of the active verb becomes the subject of the passive verb.
2. The finite form of the verb is changed (to be+ past participle).
3. The subject of the active sentence becomes the object of the passive sentence (or is dropped).
4. Preposition ‘by’ is used before object.
The given sentence is of past perfect tense and it is in active form. The structures for active/passive voices are:
Active: Subject + had + verb (IIIrd form) + object…
Passive: Object + had + been + verb (IIIrd form) + by + subject…
Hence option D is the correct answer.
