The principle says a foreign judgment binds the parties and is conclusive, unless that judgment was obtained by fraud. A obtained the US judgment by producing fake documents, which is fraud on the court that gave the judgment. The question is what that does to the judgment's effect in India.
Because the US judgment was obtained through fake documents, it falls outside the conclusiveness the principle otherwise grants, and the fraud exception opens the door to fresh litigation in India.
Therefore, the correct answer is New Suit can be filed in India on the same facts.
The one fact in this scenario that decides everything is the fraud, A got the US court to rule in his favour by producing fake documents. Every option can be tested simply by asking whether it treats that fraud as removing the judgment's conclusiveness or not.
Testing every option purely against the presence of fraud leaves only the option that opens the door to a fresh suit, since fraud is precisely what removes the judgment's binding effect.
Therefore, the correct answer is New Suit can be filed in India on the same facts.
