Although Sourav Ganguly had invited MS Dhoni, he did not come. Basic
Right Answer is: A
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…
Here the subordinate clause in the question is,
Sourav Ganguly had invited MS Dhoni,
The pattern of its passive voice is,
If + O + had + been + by + S,
So the passive voice of the subordinate clause is to be written as,
MS Dhoni had been invited by Sourav Ganguly
Hence Option A is correct answer.
